HOW CAN I DO MULTI OBJECTIVE OPTIMIZATION USING PSO?

What would the multiple objectives be? Minimize tool wear, maximize frequency for example? Suppose the optimum tool wear is not the optimum frequency?

Why do this through PSO at all when there is a simple vectorized computation for it? http://www.mathworks.co.uk/matlabcentral/answers/69077-optimization-using-particle-swarm-optimization
