Hello all

The StackOverflow site has the following question:

  Best open source mixed integer optimization solver

 "I am using CPLEX for solving huge optimization
  models (more than 100k variables) now I'd like to
  see if I can find an open source alternative, I
  solve mixed integer problems (MILP) and CPLEX
  works great but it is very expensive if we want
  to scale so I really need to find an alternative
  or start writing our own ad-hoc optimization
  library (which will be painful)

  Any suggestion/insight would be much

GLPK ranks well and the range of answers is also
interesting.  Kudos to Andrew!

cheers, Robbie
