Hi everyone I'm trying to optimize a building design, by coupling ENErgyplus and an optimisation tool GENOPT . for that , I'm using a Hybrid Generalized Pattern Search Algorithm with Particle Swarm Optimization Algorithm (GPSPSOCCHJ) for discrete and continuous variable. but I can't understand how to determine the number of the particle for this optimisation .

Please , give an idea about the mean of this parameter(NumberOfParticle ).

Thanks
