Elena Petrunina

Abstract

Approximation technologies have regained much interest in recent years in the context of wide variety of computation techniques and large scale optimization. The purpose of this study is to outline the conceptual framework and architectural design of adaptive library for approximate solutions based on multi-extremum functions. Simulation technology of complex systems includes approximation methods as estimation tools. Despite the fast development of computing power and technology, many problems of multi-extremum optimization are known to be computationally difficult. In this study we describe the adaptation library of algorithms and programs provides the realization of surrogate based modeling technique using hybrid approximation method, in which the goal is to implement sets of special functions differing in possibility of selecting special types of functions in conjunction with fast greedy algorithms or genetic optimization parameters. The adaptation library includes hybrid approximation algorithms, special models, data structures and several complete solutions for simulation various classes of approximation problems. Adaptation to these problems is based on three selection methods of calculation process: procedural, parametric and combination method. More than two hundreds approximate models and algorithms are integrated in this special models library. A problem of the environmental factors impacts on complex systems is used to demonstrate the implementation of adaptive library. We further show how several fast-rate results illustrate the usage of hybrid approximate algorithms. Furthermore, comparative analysis of hybrid algorithms has presented robustness of proposed adaptive library.
