AN APPROACH FOR SIMULTANEOUSLY DETERMINAING THE OPTIMAL TRAJECTORY AND CONTROL OF REDUCE THE SPREAD OF COMPUTER VIRUSES

Abstract

In the recent decade, a considerable number of optimal control problems have been solved successfully based on the properties of the measures. Even the method, has many useful benefits, in general, it is not able to determine the optimal trajectory and control at the same time; moreover, it rarely uses the advantages of the classical solutions of the involved systems. In this article, for a Susceptible-Infected-Removed-Antidotal (SIRA) model for viruses in computer, we are going to present a new solution algorithm. First, by considering all necessary conditions, the problem is represented in a variational format in which the trajectory is shown by a trigono-metric series with the unknown coefficients. Then the problem is converted into a new one that the unknowns are the mentioned coefficients and a positive Radon measure. It is proved that the optimal solution is exited and it is also explained how the optimal pair would be identified from the results deduced by a finite linear programming problem. A numerical examples is also given.
