Multi Objective Optimization with constraints

[prav...@gmail.com]

Hi... I am new to inspyred library. I am trying to use it to solve a bi-objective optimization problem with non-linear constraints. It seems to be a straight forward problem. However, I am not able to find any example where multi objective optimization problem has been solved(other than benchmarks). I would really appreciate if such an example can be shared.

Thanks
Pravesh

Can you describe for me your specific problem? If you can, I might be able to do better than just give an example.

Hi Professor,
Thanks for your response.
I want to solve the following
Minimize (z1 = x1, z2 = x2)
Subject to
x1**2 + x2**2 - 1 >= 0
(x1-0.5)**2 + (x2-0.5)**2 <= 0.5
0 <= x1, x2 <= 3.14

I know it's really a very basic problem. However as I told, I couldn't get any reference to implement multi objective optimization problem(other than benchamrk problems) using inspyred library and I am very new to this library. So even a template case would help.

OK. Try this as a start: https://repl.it/@agarrett/InspyredForumPost25Sep2018

It seems like you're going to have a lot of nondominated solutions for that problem, so I'm not sure what other criteria your decision maker will be using to find the actual "optimal" solution.

Thank you so much for the code. Really appreciate this.
