Аннотация: An algorithm of variable structure for solving stiff problems is constructed using L-stable and explicit methods. It is based on explicit and L-stable methods, both schemes of order two, and on an explicit method of the first order, which interval of stability is extended. On each step an efficient numerical scheme is chosen by criterion of stability. The numerical results of modeling the simplest oregonator and the modified oregonator exhibiting complicated limit cycle are given. © 2015, North Atlantic University Union NAUN. All rights reserved.
