Two class location problems of tree onto finite set are distinguished: generalized Weber problem and quadratic assignment problem. Strong polynomial algorithm for Weber problem is known. Under study special quadratic assignment problem holds good strong sense NP-hard. For it solving pseudopolynomial algorithm using Weber problem algorithm is presented. It proves rencontre of classes NP and P. It is proved that computational complexity of problem Hamilton chain does not increase value O(|V|6log2|V|).

Considers an algorithm for vonstructina an Eulerian trail for a plane Eulerian graph satisfying one global condition for the edges order. Such a graph and such a trail can be con-sidered as a mathematical model for a cutting plan. The condition on edges order means that a part cut-off a sheet does not require additional cuttings and the cut path does not intersect any not-cut path.

APPLICATION OF FACTUAL ANALYSIS OF FULL TEXT DOCUMENTS IN THE FIELD OF BUSIh2>

NESS INTELLIGENCE

Present a method of extracting factual data (objects, their attributes and relationships) from natural language texts using ontological knowledge base model. Subject area is represented through ontological model extended by fuzzy links between objects. Using this ontology-based approach, we have created Cyber-analytic, information analysis system which is capable of extracting facts from natural-language texts in Russian and English, and representing them as object relationships (person, organization, action, attribute, etc.). We use i2 Analysts Notebook as a visualization tool.

In the work, the problem of restoration of signals blurred by a linear operator is considered. An image as a function of two variables can be well described with two variations. One of them is a metrical characteristic of continuously differentiable functions. Another one is called a linear variation. The linear variation is a topological characteristic of a function of two variables. We carry out a detailed analysis of the gradient descent method for signal restoration. Restoration errors of the method can be overcome by using linear variations. Computer simulation illustrates restoration results by the gradient descent method.

The problem of recognizing of voice commands is discussed. To improve the quality of recognition the changing of amplitude spectra of signals of unfamiliar speakers to amplitude spectra of signals of familiar speaker is proposed. A heuristic technique is also proposed, which is to increase the sample values of the amplitude spectra of speech signals by a constant. The results of experiments are reported.

This projects goal is the creation of intelligent system to control the robotic object, which combines both traditional and innovative programming methods.

The main software component of the system is a finite state machine. A neural network as one of the parts of the finite state machine is designed to detect various images and modelling the behavior of the robot depending on the type of the detected object. The system can be applied to the solution of tasks and in other technological areas.
