    Problem solving in ID-logic with aggregates: some experiments

    Full text link
    The goal of the LP+ project at the K.U.Leuven is to design an expressive logic, suitable for declarative knowledge representation, and to develop intelligent systems based on Logic Programming technology for solving computational problems using the declarative specifications. The ID-logic is an integration of typed classical logic and a definition logic. Different abductive solvers for this language are being developed. This paper is a report of the integration of high order aggregates into ID-logic and the consequences on the solver SLDNFA.Comment: 9 pages conference: NMR2000, special track on abductive reasonin

    A Survey of Monte Carlo Tree Search Methods

    Monte Carlo tree search (MCTS) is a recently proposed search method that combines the precision of tree search with the generality of random sampling. It has received considerable interest due to its spectacular success in the difficult problem of computer Go, but has also proved beneficial in a range of other domains. This paper is a survey of the literature to date, intended to provide a snapshot of the state of the art after the first five years of MCTS research. We outline the core algorithm's derivation, impart some structure on the many variations and enhancements that have been proposed, and summarize the results from the key game and nongame domains to which MCTS methods have been applied. A number of open research questions indicate that the field is ripe for future work

    The Analysis of First Year Computer Science Design Documents

    Computer science is, at its core, about solving problems. The "Carry out the Plan" portion of problem solving is often examined and emphasized in CS 1 and CS 2, forgetting to emphasize the other important aspects of the problem solving process. This study focuses on the other problem-solving steps, which we refer to as design, and include “Understanding the Problem,” “Devise a Plan,” and “Creating a testing plan.” Four terms of design data (2, 797 design documents) are examined to answer the questions of how design document quality correlates to grades, whether syllabus detail impacts the quality of design documents, whether differences in design document quality diverge along demographic lines, and what attitudes students harbor toward design. The results show minimal to no correlations to grades, that syllabus detail does impact the way students design, that there are few differences based on demographic information, and that students do value design when asked in a survey. These insights have implications on when and how design is taught and opens questions on how to best assess design

    Virtual Reality Games for Motor Rehabilitation

    This paper presents a fuzzy logic based method to track user satisfaction without the need for devices to monitor users physiological conditions. User satisfaction is the key to any product’s acceptance; computer applications and video games provide a unique opportunity to provide a tailored environment for each user to better suit their needs. We have implemented a non-adaptive fuzzy logic model of emotion, based on the emotional component of the Fuzzy Logic Adaptive Model of Emotion (FLAME) proposed by El-Nasr, to estimate player emotion in UnrealTournament 2004. In this paper we describe the implementation of this system and present the results of one of several play tests. Our research contradicts the current literature that suggests physiological measurements are needed. We show that it is possible to use a software only method to estimate user emotion

    The purpose of this thesis is to develop an application to evaluate the physical and mental state of the elderly over time using different games that interact with different abilities. It will keep the progress of the results and it will also adapt the game to the level of each skill per each user
