IPAT-S now supports mixed integer linear programming (beta)
The IPAT-S interpreter now supports mixed integer linear programming (MILP). The enhancement is currently beta (version 4.9.15beta). If you are using the LP features of IPAT-S, please try it out! It must be downloaded directly from sourceforge, and not from the ipat-s.org web site.
The changes are not yet documented. To try it, use a syntax like
solve for realvar1 int(intvar1) realvar2
It is also now possible to dump an LP structure by setting the global variable _LP_PRINT_ = true. The LP structure will be output as though it were a print block.
