Hi all,

I want to minimize my 2 objective functions and have bounds for 2 variables, x1 and x2. I tested the multiobjective GA in MATLAB Optimtool by using different types of crossover - scattered, single point, two point, intermediate, heuristic and aritmetic.

The first 3 methods gave me solutions for x1 and x2 at only the lowest limit of the bounds. Meanwhile the latter 3 methods gave me various solution of x1 and x2 range within the bounds limits.

My question,

1. Which solutions are actually converge to global minima?

2. What is it mean when the solutions only show at the lowest or highest bound limit?

Thank you
