Advantages◦ Few control parameters◦ Fast convergence◦ Both exploration & exploitation

Disadvantages◦ Search space limited by initial solution (normal

distribution sample should use in initialize step)

VEABC◦ Multi-objective ABC◦ Inspired by VEGA, BEPSO

◦ Separate in to k swarm◦ Due to number of objective

◦ Evaluate each swarm to each objective

◦ Position of each swarm -> update neighbor solution

Design composite structure◦ Objectives

Minimize weight Minimize total cost Specified strength

◦ Variables Number of layers Stacking sequence Thickness of each layer

◦ Evaluation Stresses of component Failure criteria

◦ Comparison PSO, AIS, GA
