this paper introduces a new teaching tool for K-12 schools withthe aid to transfigure the way young peoples use of online data. the tool involves participators who don't have prior programming knowledge and wish to learn computational concepts as part of playing with online data. Computational thinking provides a way for solving many real-world problems that are not learned easily by using many existing tools. Map-Blocks is a software suite that combines the easy to use visual programming environment with easy to get started block shaped programming environment.

this paper presents a methodology to define the trading policy of an energy generation agent. the proposed approach uses stochastic programming to represent the uncertainty related to the short-term price fluctuation. the aim of the model (based on possible prices) is to identify the composition of an optimum portfolio in accordance withthe decision-maker risk perception. the most important contribution of this paper is the fact that the risk criteria are considered in the decision-making model. this is done through the use of tools such as Value at Risk (VaR) and the Conditional Value at Risk (CVaR). Despite the fact that the calculation of CVaR requires previous knowledge of VaR, in the proposed model both risk measures are simultaneously determined.

In this paper we argue that the traditional model of a mobile agent provides a poor programming structure. We base our argument on our experience since 1993 in building distributed applications and mobile agent platforms. We have observed that every distributed applications contain three distinct aspects, which we call function, mobility and managament. Separating an application into these three aspects and programmingthem separately affords great flexibility and leverage when designing mobile agent applications for distributed system management. Because of these observations, we have developed a programming model and a mobile agent system in which these three aspects are clearly separated.

Bilevel linear programming (BLP) is a solution method for linear optimization problem with two sequential decision steps of the leader and the follower. In this paper, we assume that the follower's objective function is imprecise and can be represented by a fuzzy function, the BLP withthe follower's fuzzy objective function (BLPwFFO). We apply the approach of necessity measure optimization to obtain the global optimal solution for the leader. this solution is not only secure but comprehensively reflects the follower's rational reaction. In the case that the follower's coefficient vector is defined by the convex polyhedron fuzzy set, our proposed BLPwFFO is formulated as a special kind of three-level programming problem. Because an optimal solution exists at a vertex of feasible region, we use the k-th best method to search for the global optimal solution. the numerical example is used to demonstrate our computational method.

In thus paper, we focus on decentralized multiobjective programming problems where multiple decision makers called the leader and the followers make decisions in their hierarchical positions and each of them have multiobjective functions. Under the cooperative relationships between the leader and the followers, the original problem is formally decomposed into the leader's multiobjective programming problem and the followers' ones. In order to deal with such multiobjective programming problems, the extended Pareto optimal concepts are introduced, called the leader's Pareto optimal solutions and the corresponding followers' ones which are defined in membership function space. An interactive fuzzy decision making method is proposed to obtain the satisfactory solution which reflects not only their preferences but also their relationships in some sense. the numerical example illustrates the proposed method under the hypothetical interactions between the leader and the followers.

We present a massively parallel algorithm for computing persistent homology, a concept within the field of topological data analysis, and we implement it in the purely functional array-based language Futhark, which has an efficient compiler targeting GPUs. Computing persistent homology consists of bringing a certain sparse matrix to a reduced form. We compare our implementation with OpenPH, an existing library for computing persistent homology on GPUs, and on large matrices we achieve speedups of 2.3 to 5. Our work shows boththat persistent homology can be computed efficiently entirely on GPU hardware, and that Futhark can be used for this kind of sparse matrix manipulation.

the aim if this paper is to show relationships between different formalism for handling uncertainty in logic programming, knowledge based systems and deductive databases. Namely we show that our model of fuzzy logic programming has same expressive power as annotated logic programs with restricted continuous semantics. Features of fuzzy unification are achieved by extending the rule base by axioms of equality with fuzzy similarities, this induces a new fuzzy relational algebra. Our procedural semantics enables to estimate truth values of the answers during the computation. Using this we introduce a model withthreshold computation and an another for finding the best answer with prescribed precision tolerance.

In this paper we deal with a transportation problem in a housing material manufacturer. the housing material manufacturer entrusts transportation of its products to two forwarding agents which handle regular transportation and small lot transportation. there are two objectives of the housing material manufacturer: one is to minimize the transportation cost and the other is to minimize the opportunity loss with respect to transportation time. Each of the two forwarding agents assigns drivers the transformation tasks so as to maximize its profit. We formulate the problem as a decentralized two-level integer programming problem and apply interactive fuzzy programming.

In this paper, we focus on a decentralized two-level multidimensional 0-1 knapsack problem with block angular structure involving a single decision maker (DM) at the upper level and multiple DMs at the lower level and apply an interactive fuzzy programming to derive a satisfactory solution in cosideration of balance between the satisfactory level to the DM at the upper level and those to the DMs at the lower level. Since it is shown that all of problems solved to the interactive fuzzy programming have block angular structures, we propose the introduction of a genetic algorithm with decomposition procedures for the purpose of utilizing the special structure of the problems.
