مقایسه نه الگوریتم متاهیوریستیک برای طراحی بهینه سازه خرپا با محدودیت های فرکانس

This paper compares nine multi-agent meta-heuristic algorithms for sizing and layout optimization of truss structures with frequency constraints. The variation of the diversity index during the optimization history is analyzed in order to inspect exploration/exploitation properties of each algorithm. It appears that there is a significant relationship between the algorithm efficiency and the evolution of the diversity index.
