Documenting common and most important options across all solvers

[fdabrandao]

It would be good to list the most important and common options across solvers so simplify solver tuning when testing multiple solvers.

• Some important options to start with:

  • timelimit
  • mipgap
  • mipgap
  • method/lpmethod
  • crossover
  • basis
  • solutiontarget (Gurobi only)
  • mipfocus (Gurobi only)
  • numericfocus (Gurobi only)
  • intfocus (Gurobi only)
  • feastol
  • inttol
  • stub
  • scale
  • mip:return_gap (already listed in the features)
  • Done, see section in the MP doc’s Features Guide:
    https://mp.ampl.com/features-guide.html#important-features
  • Linked from every solver’s doc, e.g.,
    https://dev.ampl.com/solvers/gurobi/index.html#resources

• Colab notebooks illustrating such options with some solvers
