change number of pareto point with change number of initial population gamultiobj

Hi, I had a question for you, why in a multi-objective genetic algorithm, the number of Pareto points changes with the change in the number of population members?

You asked the exact same question very recently:
Please don't ask the same question multiple times.
As for the answer, generally the larger the population size, the more points on the Pareto front. In gamultiobj, for example, the ParetoFraction option keeps the fraction of population members on the front at 0.35 by default. So clearly a population size N will have approximately 0.35N members on the front.
