Hi, my code is running through fine, and I am getting a pareto front output from the algorithm. The problem is that when I run the output (x) through my cost function it gives a different cost than the gamultiobj algorithm said it was.

For instance when the algorithm is done it give x=2, with cost =[2 3 5],

Then I run cost_function(2) and it gives cost=[1e3, 1e3, 1e3] for example.

My code is more complicated than that, but that is the issue I am getting

Thanks

Kurt - you may need to provide more details (and/or code) describing how you are setting up the GA.

My code is pretty long - and also I can't share much of it for propietary reasons. Wondering if anyone had this type of issue. I am using a try-catch in my cost function could this be causing problems?
