• TITLE: On Metaheuristic Optimization Motivated by the Immune System

  AUTHORS: Mohammed Fathy Elettreby, Elsayd Ahmed, Houari Boumedien Khenous

  KEYWORDS: Multiobjective Optimization; Extremal Optimization; Immunememory and Metaheuristic

  JOURNAL NAME: Applied Mathematics, Vol.5 No.2, January 20, 2014

  ABSTRACT: In this paper, we modify the general-purpose heuristic method called extremal optimization. We compare our results with the results of Boettcher and Percus [1]. Then, some multiobjective optimization problems are solved by using methods motivated by the immune system.
