This paper describes a few ideas concerned with geographical information systems (GIS) development. Those ideas come from a GIS development project named GeKon, which is now held on the Department of Computer Science at CTU. The first of them deals with a huge semantic gap between the complex structure of real world and its representation in GIS. Some papers describe this problem as a consequen...

This paper presents an algorithm for induction of ensembles of decision trees, also referred to as decision forests. In order to achieve high expressiveness the trees induced are multivariate, with various, possibly user-defined tests in their internal nodes. Strongly typed genetic programming is utilized to evolve structure of the tests. Special attention is given to the problem of diversity o...

We consider herein a concise view of discreet programming models and methods. There has been conducted the models and methods analysis. On the basis of discreet programming models there has been elaborated and offered a new class of problems, i.e. block-symmetry models and methods of applied tasks statements and solutions. Keywords—Discreet programming, block-symmetry, analysis methods, informa...

In this work, we present a short review about the high level design methodology (HLDM), that is based on the use of very high level (VHL) programing language as main, and the use of the intermediate level (IL) language only for the critical processing time. The languages used are Python (VHL) and FORTRAN (IL). Moreover, this methodology, making use of the oriented object programing (OOP), permi...

Dynamic programming seeks to solve complex problems by breaking them down into multiple smaller problems. The solutions of these smaller problems are then combined to reach the overall solution. Deterministic algorithms have the advantage of accuracy but they need large computational power requirements. Heuristic algorithms have the advantage of speed but they provide less accuracy. This paper ...

A key element in the design of Intelligent Tutoring Systems (ITS) is to fit the learning plan to the individual variances of learners. We studied this problem by modeling a dependency relationship between concepts of a Java programing course within a Bayesian network. Our model was established on the basis of experts’ views, corroborated by experimental investigation. We found that the tested p...

A Boolean function is a function that produces a Boolean value output by logical calculation of Boolean inputs. It plays key roles in programing algorithms and design of circuits. Minimization of Boolean function is able to optimize the algorithms and circuits. Quine-McCluskey (QM) method is one of the most powerful techniques to simplify Boolean expressions. Compared to other techniques, QM me...

Heterogeneous multi-core processors are at tracted by media processing applications due to their ca pability of drawing strengths of different cores to improve the overall performance. However, the unavailability of an efficient programing environment is a major problem. In this paper, we propose an FPGA-oriented heterogeneous multi-core processor, with GPU-like accelerator cores. We use a CUDA...
