The Event

As part of Global Goals Week, the Skoll Foundation and the United Nations Foundation are pleased to present We the Future: Accelerating Sustainable Development Solutions on September 21, 2017 at TED Theater in New York.
The Sustainable Development Goals, created in partnership with individuals around the world and adopted by world leaders at the United Nations, present a bold vision for the future: a world without poverty or hunger, in which all people have access to healthcare, education and economic opportunity, and where thriving ecosystems are protected. The 17 goals are integrated and interdependent, spanning economic, social, and environmental imperatives.
Incremental change will not manifest this new world by 2030. Such a shift requires deep, systemic change. As global leaders gather for the 72nd Session of the UN General Assembly in September, this is the moment to come together to share models that are transforming the way we approach the goals and equipping local and global leaders across sectors to accelerate achievement of the SDGs.




Together with innovators from around the globe, we will showcase and discuss bold models of systemic change that have been proven and applied on a local, regional, and global scale. A curated audience of social entrepreneurs, corporate pioneers, government innovators, artistic geniuses, and others will explore how we can learn from, strengthen, and scale the approaches that are working to create a world of sustainable peace and prosperity.

Mazes increase in complexity and programming requirements, encouraging students to learn more about Prolog and to be creative with the way they construct the AI. Section 11.6 considers applications of an integration of CLP(R) and abduction for reasoning on continuous change and resource planning. It bears a similar relationship to computer science and engineering as mathematical logic bears to mathematics and as philosophical logic bears to philosophy. One solution is to modify and extend the syntax of CLP languages to be closer to standard mathematical modeling. He used abduction to solve planning problems in the Event Calculus [Kowalski and Sergot, 1986]. Computational thinking has also begun to influence disciplines and professions beyond science and engineering. Approaches include better compilation, local and global analysis, and programmer mode and type declarations [42]. These keywords were added by machine and not by the authors. The associated set of regression tests that need to be conducted on the repaired software product must be identified. ), that lets them solve the first mazes. : 2. using computers to study…. See more. Most controversial perhaps will be our decision to include modal and intuitionistic logic in an introductory text, the inevitably cost being a rather more summary treatment of some aspects of classical predicate logic. This system gives support to a first-year subject whose aim is to introduce students to computational logic. Software unit test scenarios. Philosophers of mathematics often distinguish between first-order logic and second-order logic only. So the idea for IFCoLog is the same as in AI and most other scientific fields these days: An International Federation for Computational Logic (IFCoLog)20 has been created more than twenty years ago with the help of Dana Scott and legally registered in the Netherlands as well as a charity in London with the financial aid of the European Network of Excellence for Computational Logic (CologNet and COMPULOG), whose members are the current (and future) communities related to computational logic. There are different views on what an explanation is. Fuzzy Membership Values reflect the membership grades in a set. 12 and to replace the loop with a deterministic data access pattern. In as much as the Federation aims to counterbalance the growing division in the field and to represent it once again in its entirety, it is working on the four major goals: Information, Representation, Promotion and Cooperation. They provide powerful and flexible search control and modern CLP languages provide a variety of techniques, such as attributed variables, indexicals, CHRs, for extending the constraint solver. Indeed, over the last 30 years, shock-fitting methods have experienced an increasingly widespread ostracism, mainly caused by the fear of the difficulties posed by the implementation of the shock-fitting logic. This effort resulted in a model of a significant portion of the Java Card subset of the JVM. The system is an extension of Horn clause resolution-based logic, and is devised in a way that makes important features of reflection parametric as much as possible, so that they can be tailored At the simplest level, computers are little more than a collection of transistors and circuits. The term abduction has been used to cover hypothetical reasoning in a range of different settings, from human scientific discovery in philosophical treatments of human cognition to formally defined reasoning principles in formal and computational logic. This paper also clarified the role of total versus partial order, and showed how to implement a correct partial order planner by extending the abductive solver with a constraint solver CLP(LO) for the theory of total order (or linear order). Hence, abduction is strongly related to model generation and satisfiability checking: it is a refinement of these forms of reasoning. Each ECR should include the necessary specification and documentation change pages that will be used to assimilate the change into the architectural artifacts, and documentation consistent with the proposed change, if approved. In Event Calculus, predicates describe the occurrences of actions and their order (event = occurrence of an action). Computational tree logic Computation tree logic (CTL) is a branching-time logic , meaning that its model of time is a tree-like structure in which the future is not determined; there are different paths in the future, any one of which might be an actual path that is realized. The chronological backtracking search model of CLP languages needs to be combined with local search techniques in which the search state is updated by local changes. With the growing unification of Europe there are currently more than two dozen members, who represent all European AI researchers and whose representatives meet every two years at the time of ECAI, the European Conference on Artificial Intelligence. According to this view, algorithms consist of a problem description (the logic part) along with a strategy to carry out useful computations on this description (the control part). These control structures have comparable constructs implemented by most computer languages. At the time of writing we have applied with positive response for membership in the International Council for Science (ICSU) in order to realize our final goal, namely to establish computational logic as an academic field of its own. As a conclusion, we believe it may be time to refocus the efforts of a larger number of CFD developers on a technique that is able to ensure results that are qualitatively superior to those that shock-capturing methods can deliver. A more correct view is that an explanation gives a cause for the observation [Josephson and Josephson, 1994]. Abduction has been proposed as a reasoning paradigm in AI for fault diagnosis [Charniak and McDermott, 1985], natural language understanding [Charniak and McDermott, 1985], default reasoning [Eshghi and Kowalski, 1989], [Poole, 1988]. Unit test scenarios describe how a software unit will be verified to confirm that it satisfies its structural unit specification. The poor quality of the solutions obtained using these methods, when discontinuities are present, is their main weakness. We want to establish a permanent office for the federation that coordinates and maintains all of these activities similar to, say, the Royal Society for Science in Great Britain or the scientific academies in various countries. Arguably, the modeling language OPL can be viewed as a (very) restricted CLP language. This is a preview of subscription content, © ECSC, EEC, EAEC, Brussels and Luxembourg 1990, https://doi.org/10.1007/978-94-009-0705-8_59. theory. In the context of logic programming, abductive procedures have been used for planning [Eshghi, 1988a], [Shanahan, 1989], [Missiaen, 1991a; Missiaen et al., 1995], knowledge assimilation and belief revision [Kakas and Mancarella, 1990a; Kakas et al., 1992], database updating [Kakas and Mancar-ella, 1990b]. Some results of particular interest: Preliminary Formal Definition of the Java Virtual Machine In collaboration with Javasoft and Schlumberger Electronic Transactions, Computational Logic is pleased to make available a draft formal model of the Java Virtual Machine. When they achieve more than 75% on a given maze, they unlock the next one and can continue. ic (lŏj′ĭk) n. 1. Information and translations of computational in the most comprehensive dictionary definitions resource on the web. The difficulty of programming in CLP languages was identified as a problem in [91]. Software problem reports. Abstract. What does computation tree logic mean? These features, especially the ability to quantify over predicates, profoundly influence the proof-theoretic structure of the logic. The outline of the chapter is as follows. This semantics must account for optimisation, reflection, search, and constraint handling. Computation and Logic Definitions True and False Also called Boolean truth values , True and False represent the two values or states an atom can assume. Logic is a set of principles that forms a framework for correct reasoning. The definition can be used bottom-up to derive a se- quence of assertions about factorial or it can be used top- In our application, for example, the Pressure Tendency block consists of a 3D loop whereas the surface pressure is reduced over the altitude in 2D. Software component assembly, integration, and test procedures. Within the Compulog basic research action we use the term to mean the use of logic as a broad spectrum language for programs, program specifications, databases, and “knowledge bases” in artificial intelligence. Partially solved mazes also contribute to their final grade proportionally to the percentage of the maze solved. © 2020 Springer Nature Switzerland AG. Meaning of computational. For this reason, it is important to understand the data dependency among the different parts of the algorithm. Logic & Computation is a Bachelor of Science degree. Section 11.7 briefly explores the limitations of abductive reasoning. from computational logic to implement these algorithms, and thereby to help build, refine, test or apply new ideas in semantics. For instance, the CLP language ECLiPSe provides iteration allowing conceptual modeling closer to traditional modeling languages. When the student is already satisfied with her/his he submits its to/he submits its to PLMan gamified web (5), immediately obtaining the correction and results (6). Computational Logic Inc. 1717 W. 6th St. Suite 290 Austin, Texas 78703 (512) 322-9951 This research was supported in part by the U.S. Government. Moreover, despite these great efforts that involved a large number of scientists, the shock-capturing drawbacks have not been completely overcome. When embedded in computational logic, core functional traits like lightpath routing,will be performed aiming at better resource utilization from an energy perspective. Computational Logic centers around the famous definition: Algorithm = Logic + Control. These mazes are organized into four main stages and five levels of difficulty per stage. Within the functional architecture, control structures represent the decision or computational logic that determines how the data processing execution should proceed. By restricting the explanation formulas to the predicates describing primitive causes in the domain, an explanation formula which entails an observation gives a cause for the observation. Student-centered information’s flow of PlMan system. The software integration strategy should be detailed by establishing the procedures necessary to compile, assemble, and link (integrate) source code files into an executable file to support software component testing. computational definition: 1. involving the calculation of answers, amounts, results, etc. This formal definition implements the logical entailment view on abductive explanations. The efforts of many CFD developers have rather been focussed on counteracting the flaws and shortcomings of the shock-capturing technique; in doing so, however, shock-capturing algorithms have lost some, if not most, of their algorithmic simplicity. n. 1. a. The first would require a very large buffer to temporary store the full problem size. pp 768-773 | As summarised in Roe's words Roe (2011): “a reappraisal of fitting methods is timely”, since“a revival of shock-fitting is one of the few remaining possibilities for revolutionary change [in high-resolution methods]”. Figure 10B shows the reordering of the logic that was required for the dataflow transformation. At her/his local computer and after installing SWI-Prolog and downloading PLMan, the student programs the AI to solve the maze and tests it (3), showing the results and the necessary information to fix bugs (4). Yet a third, is to build a modeling language on top of the CLP systems. The tasks that will be considered are (ambiguous) prediction, (ambiguous) postdiction and planning problems. Students have to beat the four stages and a checkpoint in the system to get the maximum grade. This fact prevents the merging of the 3D loops in the Pressure Tendency and the Diaged blocks. Fuzzy Logic is the logic of approximate reasoning. Often Abduction is defined as “inference to the best explanation” where best refers to the fact that the generated hypothesis is subjected to extra quality conditions such as (a form of) minimality or maximality criterion. Deviations do not relieve the program from achieving the specified requirement, but will permit the initial release of the software product with an understanding that the problem will be corrected in a future patch or release. We mention below three different groups of people who appear to use this term in three different ways. Information and translations of computation tree logic in the most comprehensive dictionary definitions resource on the web. Combining loops for more efficient dataflow. A source code file is intended to be compiled into an executable binary file that can be run on the target computing system. At each stage, students have to solve one to five different mazes (depending on the stage). With that in mind, one could develop more specific definitions of a programming logic having to do with the basis of a piece of code. When embedded in computational logic, core functional traits like lightpath routing,will be performed aiming at better resource utilization from an energy perspective. Another more illustrative example is cited from [Psillos, 1996]: the disease paresis is caused by a latent untreated form of syphilis, although the probability that latent untreated syphilis leads to paresis is only 25%. The linguistic problems of meaning are not limited to judgments of truth conditions, however. In automata theory, combinational logic (sometimes also referred to as time-independent logic ) is a type of digital logic which is implemented by Boolean circuits, where the output is a pure function of the present input only. However, fragmentation can carry a heavy price intellectually as well as politically in the wider arena of scientific activity where, unfortunately, logical investigations are often still perceived as limited in scope and value. Unit test scenarios should be developed and documented in the software development folders (SDFs). Because of this, students do not have a limit of submissions for a given maze. CLP is now a cornerstone of logic programming theory, systems and applications. Along with the practical lessons of the subject, students use Prolog (Sterling and Shapiro, 1994) as logics programming language. computational ideas pervade their syllabuses. The software component test scenarios and procedures should be described and captured in a component SDF. It is a generalization of conventional logic. In all these cases, we illustrate how abductive reasoning can help to explore the space of possible evolutions of the world. In general, ε may be subjected to further restrictions: the aforementioned minimality criteria, but more importantly criteria on the form of the explanation formula. Definition of computational in the Definitions.net dictionary. A major strength of CLP is a simple, elegant declarative semantics which brings together logical, algebraic and operational viewpoints. In a postdiction problem, the problem is to infer some information about the initial state or the events using complete or partial information on the state of affairs at later stages. ACM Monograph Series: A Computational Logic focuses on the use of induction in proving theorems, including the use of lemmas and axioms, free variables, equalities, and generalization. This report will be used in determining the readiness of the software product for operational deployment. Because so much of the programming and hardware world depends on mathematical operations, there are seemingly infinite ways to apply computational mathematics to computer science. Numerous practical applications of different shock-fitting methods developed by the authors over the years, using both structured- and unstructured-grid gasdynamics solvers, have been presented in this chapter, demonstrating that these methods can be effectively used to simulate complex two- and three-dimensional flow fields. [Shapiro, 1985]). From this theorem it follows that second-order logic is necessarily incomplete: that is, truth in higher-order logic can not be recursively axiomatized. One part of the section is devoted to representing different forms of uncertainty in the context of event calculus and showing how abduction can be used to solve different sorts of tasks in such representations. Cite as. Programming logic in general rests on a foundation of computational logic that is shared by both humans and machines, which is what we explore as we continue to interact with new technologies. This process is experimental and the keywords may be updated as the learning algorithm improves. Also, elaborate comparison and evaluation between heuristic methods can be achieved through simulation. This is notably the case in model-based diagnosis and in temporal reasoning, where theories describe effects of actions. A mode of reasoning: By that logic, we should sell the company tomorrow. The term “computational logic” has no generally agreed definition. See more. Proof-theoreticians take logic to be synonymous with a formal system that provides a recursive enumeration of the notion of theoremhood. However, in many applications of abduction in AI, the theory 𝒯 describes explicit causality information. It is worth summarizing the strengths of CLP. From the operational model perspective, control structures represent business rules or operational procedures that determine how a process should be executed. The logical-algebraic structure associated with classical mechanics admits the definition of a probability measure over it with its elements considered as events. All of them have been gathered into a gamified, automatic, web-based system that manages the progress of students in their practical assignments with PLMan. Another approach is to explore the use of a problem-domain specific visual front ends. Computational Logic is the process of designing and analyzing logic in computer applications. Computational logic is the use of logic to perform or reason about computation. The latter logic, which is used as a formal basis for all of mathematics, involves quantification over the domain of all possible functions. A postdiction problem is ambiguous if the initial state is not uniquely determined by the final state. Here, the observation corresponds to the desired final state. The acceptance testing report should summarize the test results, problems, and defects encountered (there should be no problems or defects encountered!). This approach was further explored by Shanahan [Shanahan, 1989], Missiaen et al. For this purpose, a game called PLMan (Castel et al., 2009) is used. As we have seen, a problem \(X\) is taken to be ‘complex’ in the sense of computational complexity theory in proportion to how difficult it … Marc Denecker, Kristof Van Belleghem, in Foundations of Artificial Intelligence, 2005. If they fail, they can continue developing and submitting solutions until they succeed. Each software problem or defect should be assigned to the organization responsible for resolving the issue. F. Llorens-Largo, ... R. Molina-Carmona, in Formative Assessment, Learning Data Analytics and Gamification, 2016. According to this view, algorithms consist of a problem description (the logic part) along with a strategy to carry out useful computations on this description (the control part). Semantical methods can also be employed, but the collection of models must now include non-standard models that use restricted function spaces in addition to the standard models used for second-order logic. An abductive explanation for a goal representing the final state is expressed in terms of these primitive predicates and provides a plan (or possibly a set of plans) to reach the intended final state. Definition: Fuzziness Fuzziness: Non-statistical imprecision and vagueness in information and data. The enormeous diversity outlined above is not necessarily disadvantageous, as every of these evolved communities addresses its own important set of problems and issues, and it is clear that one group cannot address them all. Over 10 million scientific documents at your fingertips. Software unit source code files. The products identified in this section do not represent the complete set of products generated during software implementation. This differs from artificial intelligence in its perspective on imperfection: computational intelligence focuses on the growth of a system and does not use Boolean values (0s … There are three pre-requisite courses that students will take to prepare them in computer science, mathematics and statistics. The aim is therefore to group all the, Control structures provide the means for guiding execution flow to perform a data processing task accounting for the conditional treatment of data processing intermediate results. Thus, higher-order logic interpreted in this sense consists largely of a model-theoretic study, typically of the standard model of arithmetic (cf. In the presence of incomplete information, deduction is the reasoning paradigm to determine whether a statement is true in all possible states of affairs; abduction returns possible states of affairs in which the observation would be true or would be caused. However, CLP languages have some drawbacks, which are driving the current research programs in this area. The following artifacts identify the software implementation artifacts that concern the software engineering effort: Software unit programmatic design diagrams. Not logged in One view is that a formula explains an observation iff it logically entails this observation. Jörg Siekmann, in Handbook of the History of Logic, 2014. It has also received substantial interest from researchers into computational logic and has had considerable impact on database research, and we believe an increasing impact on modeling language design.
