Description

Hello!
So, if I run cuopt_cli on an mps instance - is there a way to:

  1. Apply only MIP primal heuristics
  2. Apply only MIP primal heuristics that don't involve solving SubMIPs(eg: disable LNS/RINS)
  3. Actually see which MIP primal heuristics found the best/first solution?
    What are the flags and can you give me a sample command or tell me where should I look for this in the documentation?

Thanks
