Is there any function to set the initial value for the Integer Linear Programming (ILP) problem?

[HuangGuanSteve]

To solve a very complicated ILP problem, I have to use a greedy method to work out an initial value set. How can I apply this initial value set to the Solver? Thank you for your help.

You can add one or more starting points using something like this:

    Variable[] vars = …;
    double[] startPoint = …;
    Solution startSolution = scip.createSol();
    scip.setSolVals(startSolution, vars, startPoint);
    scip.addSolFree(startSolution);

but be warned that SCIP will do nothing with your solution if it is not feasible (at least to the tolerance).

It's my honour to get your support. Thank you.

The initial value is calculated by a greedy method that fully obeys the constraints. I can guarantee its feasibility. I will try your suggestion first.
