Function with array input

[Gerkamspiano]

This sounds like some quite heavy numerical work. Is there a reason you're not using NumPy and SciPy if appropriate? Since you're mentioning maximisation, I wonder if anything in scipy.optimize is relevant.

Thank you for your answer. I did not mention my objective. I am trying to carry on a land-use spatial optimization problem where each variable x is a binary decision about using land "j" on parcel "h". The algorithm, due to the complexity is heuristic and is based on genetics and not always leads to an optimal solution, but aproximated. I think scipy is more for traditional simple optimization problems, no?
