Abstract

In the present study, some modifications on the firefly algorithm are presented to
improve its performance. The firefly algorithm is a recently developed robust metaheuristic
optimization technique which mimics the social behavior of fireflies based on their flashing
characteristics. To improve its performance three basic modifications are proposed in the present
work. These modifications consist of adding memory, adding newborn fireflies and proposing a
new updating formula. To evaluate the applicability of the proposed method, three classical
engineering design optimization problems and three sizing optimization of truss structures are
solved and results are compared with those available in the literature. It is observed that the
proposed method can effectively be used in solution of engineering design optimization problems.
