چکیده

A software information system S allows users to store, retrieve and process information about the external world, typically in the form of a data base. We can differentiate two separate aspects in the data elaborated by S: the first concerns data types, while the second is related to the information on the external “real world” carried by the data. More precisely, a data type is a set of data together with the associated manipulations where the focus is on operations. In contrast, the other information carried by the data stored in S is strongly related to their meaning in the real world. The need for properly treating data according to their meaning is becoming increasingly important, due to the wide quantity of information exchanged on the Internet [5]. In this context, we are developing COOML [4] (Constructive Object Oriented Modeling Language), an OO specification language where the focus is on the information carried by data. The main features of COOML are:

Snapshot Generation in a Constructive Object-Oriented Modeling Language

CooML is an object-oriented modeling language where specifications are theories in a constructive logic designed to handle incomplete information. In this logic we define snapshots as a formal counterpart of object populations, which are associated with specifications via the constructive interpretation of logical connectives. In this paper, we introduce the “snapshot semantics” of CooML and we...

Learning Constructive Primitives for Online Level Generation and Real-time Content Adaptation in Super Mario Bros

Procedural content generation (PCG) is of great interest to game design and development as it generates game content automatically. Motivated by the recent learning-based PCG framework and other existing PCG works, we propose an alternative approach to online content generation and adaptation in Super Mario Bros (SMB). Unlike most of existing works in SMB, our approach exploits the synergy betw...

Design of Fuzzy Logic Based PI Controller for DFIG-based Wind Farm Aimed at Automatic Generation Control in an Interconnected Two Area Power System

This paper addresses the design procedure of a fuzzy logic-based adaptive approach for DFIGs to enhance automatic generation control (AGC) capabilities and provide better dynamic responses in multi-area power systems. In doing so, a proportional-integral (PI) controller is employed in DFIG structure to control the governor speed of wind turbine. At the first stage, the adjustable parameters of ...

Classical Logic and the Curry–Howard Correspondence

We present the Curry–Howard correspondence for constructive logic via natural deduction, typed λ-calculus and cartesian closed categories. We then examine how the correspondence may be extended to classical logic and non-constructive proofs, and discuss some of the problems and questions that then arise.

Inductively generated formal topologies

Formal topology is today an established topic in the development of constructive, that is intuitionistic and predicative, mathematics. Many classical results of general topology have been already brought into the realm of constructive mathematics by using formal topology and also new light on basic topological notions was gained with this approach which allows distinction which are not sensible...
