C++ (Cpp) OsiSymSolverInterface::resolve Examples

Example #1

File: warm_start2.c Project: hrishikeshvganu/SYMPHONY

int main(int argc, char **argv)
{

  OsiSymSolverInterface si;
  CoinWarmStart *ws;

  si.parseCommandLine(argc, argv);
  si.loadProblem();

  si.setSymParam(OsiSymKeepWarmStart, true);
  si.setSymParam(OsiSymNodeLimit, 100);

  si.initialSolve();
  ws = si.getWarmStart();
  si.setSymParam(OsiSymNodeLimit, 1000);

  si.resolve();

  si.setObjCoeff(0, 1);
  si.setObjCoeff(200, 150);
  si.setWarmStart(ws);

  si.resolve();

  return(0);

}

  si.setSymParam(OsiSymFindFirstFeasible, true);
   /* set node selection rule to DEPTH_FIRST_SEARCH */
  si.setSymParam(OsiSymSearchStrategy, 3);

  si.initialSolve();
