Feature request: elastic constraints

Open nick-gorman opened this issue 5 years ago • 2 comments

Hi,

I'd like to suggest an elastic constraints feature, like the one pulp has:

https://pythonhosted.org/PuLP/pulp.html#elastic-constraints

Cheers, Nick

This does not seems difficult to implement.

Hi guys, I used to work with CPLEX in the past as well, and there's a big improvement in terms of the relaxation model.

first there is a IIS algorithm to report infeasibilities

  1. IIS algorithm

There's also an elastic relaxation module (conflict_refiner which I'm not familiar if there's a paper about it.

  1. conflict_refiner
  2. feasOpt Algorithm

There's any open request for some of this features ?, I'm not personally working with this type of problem, but maybe there is already an implementation that we can copy. Thoughts ?

Many thanks to the developers behind this project !
