Hi,

I'm trying to optimize a mutli-objective model with the lexicographic order. Normally it works very well but when i normalize the objectives to obtain them between 0 and 1, it gives me curious results...

Indeed, the resolution stop very quickly and doesn't find good results for the 3 last objectives (they are 5). Is there a way to surpass it ?

Thanks,

DeFersen.

Hello Axel,
I think we will be better able to help you if we have your model (at least the .cpo file), and the result that you describe as "curious". Could you send them?

Hi,

Sorry for my late response.

After making some changes in my model, i don't have this problem anymore so i must have made some mistakes for sure...

Thank you for help.
