Efficiency of Evolutional Method fur Job-Shop Scheduling Problem Solution
The Evolutional Methods are used very successfully for solving NP-hard problems of discrete optimization in many applications of design and logistics. The paper is devoted to the comparison of Efficiency of Evolutional Methods such as Panicles Swarm Optimization, Ant Colony Optimization and Genetic Algorithms. The comparison is worked out on the example of Job-Shop Scheduling Problem Solution.

Way of Generation of Heuristics for the Decision of NP-difficult Tasks
In article the way of generation of heuristics is stated on the basis of statistical research of optimum decisions of NP-difiicult tasks on graphs with the small order and the size Received hcuristics allow ordering a choice of variants of decisions of HP-difficult tasks on graphs with the big order and the size. The general description of a way is added with examples of a deduction of formal heuristics and quantity indicators of a positive effect that it give at comparison with known heuristics.

Computer Banks of Knowledge. A Unified Approach to Information Editing
The aim of this work is to develop a notion of a unified tool meant for editing Information of Different Extents of Abstraction (IDEA Editor) and providing information carriers with necessary intelligent support during the editing process. Principal requirements on the unified IDEA Editor are formulated. A conceptual description of the unified IDEA Editor that meets the stated requirements is proposed.

Information Characteristics of the Entangled Slates of the q-Bits
In article information characteristics of the entangled states are analyzed. The information of communication of two q-bits is estimated. States with the maximal communication, the multivariate entangled stales of a general view are described. It is shown, that uncertainty at spatial transformations of the entangled states is kept. The model of quantum mechanics Hugh Everett is described in terms of the entangled states. It is shown, that classical objects can have information characteristics identical to characteristics of the entangled states. It is offered to use the entangled states for parallel performance of operations.

On the Choice of Metrics far Measuring the Effect of Compiler Modifications on Performance
Preventing performance degradations during compiler development is one of the key problems that should be solved to obtain a competitive compiler. In this paper we present a classification of compiler performance characteristics. Also we present a study on metrics that can be used for measuring the effect of changes introduced to a compiler on its performance. Finally, we discuss allowance thresholds for measured degradations.

Analytical Forms of Signal Processing/fir IMS Based on Generalized Modification of Fourier Transformation
Generalized modification of traditional Fourier transformation (rotational Fourier transformation, — RTF) introduced by mathematicians comparatively long ago, remained long unknown in signal processing community where RFT has not small potential for applications. RTF depends on parameter a and is interpreted as time-frequency plane rotation. For a = ¶/2 RFT is usual Fourier transformation, for a = 0 — identity operator, and the angles of RFT being implemented sequentially are additive (as the angles of successive rotation). In analytical representation, RFT is the series expansion of signal on the basis consisting of set of signals with rapidly changing frequency (on SRCF-components). The theory base elements for RFT, its properties, types of interpretation as operator, interdependence ratios of RFT with time-frequency distributions of non-stationary signals (with Wigner', short-time Fourier distributions and with spectrogram). These ratios have closed analytical forms. RFT examples for some signals and RFT applications are given.

The New Principle for Optimization of Information Systems of Remote Sensing in Transit Regimes
In the article The new principle for optimization of information systems of remote sensing" (he combined principle including well — known method of Gauss — Zaidel, variation calculation and mathe-matic analysis method is proposed. It is shown, that if the separable functional are used as criterion of effectiveness, in some cases analytical solution of the problem of optimization of the remote sensing system on energetic — information criterion may be obtained.
