How can I make customized permutation problem?

[skyblue0807]

Hello, all.

I hope to solve permutation problem with GA in pymoo, but in PERMUTATION page, there are only examples using "create_random_TSP/flowshop" function.

I have elements to be permutated, and object functions to evaluate permuated elements list.

How can I build my custom problem in pymoo?
what type of problem class should I use?

Just check out how the TSP problem is implemented in pymoo itself. You can find the source code here:
https://github.com/anyoptimization/pymoo/blob/main/pymoo/problems/single/traveling_salesman.py

For a custom problem also check out the getting started guide:
