Rapid growth of its size (thousands of points) is the main feature now, and many extensions of this problem with specific properties are studied: dynamic vehicle routing problems; systems with call (the first-aid, the courier's, the taxi), systems with time windows, and systems of delivery. They need development of the special algorithms, which provide high-quality solutions in reasonable time. That is why subsequent perfection of existing algorithms and development of new ones is relevant. In this paper, a set of strategies were proposed and evaluated, in order to solve specific TSP problems in which the points are under the form of clusters.Item Self-organising map as a tool of modelling the design parameters of microelectronics devices for ensuring the specified temperature condition(Українські технології, 2006) Bilas, O.; Levus, E.; Yakovyna, V.Using Kohonen maps the analysis and visualisation of thermal management task for flip-chip microelectronic devices have been carried out.

Self-similarity is a scale invariant property under timescale translation, i.e. it yields the existence of clustering and bursty characteristics in the flow over wide time scales. Thus, self-similar traffic causes larger queuing delays than the estimation by Poissonian traffic. Selfsimilarity is relatively a new concept in the computer networking community. It is very different from past views that considered computer network traffic as a Poisson process. In the case of self-similarity, burstness is present in all time-scales and does not tend to pure white Gaussian noise.Item Distributed ontologies structural-time analysis system(Lviv Polytechnic National University, 2006) Pavlov, D.There is emphasized actuality of developing ontological structures research.
