Purpose
Loads a starting MIP solution for the problem into the Optimizer.
Topic areas
Solution, MIP Entities, Data Input
Synopsis
status = problem.loadMipSol(x)
Argument
|
x
|
Double array of length
COLS (for the original problem and not the presolve problem) containing the values of the variables.
|
Return value
|
status
|
The status. The status is one of:
|
-1
|
Solution rejected because an error occurred;
|
|
0
|
Solution accepted.
|
|
Further information
1. When a solution is loaded, the solution is placed in temporary storage until the MIP solve is started. Only after the MIP solve has commenced and any presolve has been applied, will the loaded solution be checked and possibly accepted as a new incumbent integer solution. There are no checks performed on the solution before the MIP solve and the returned status in
problem.loadMipSol will always be
0 for accepted.
2. Loaded solution values will automatically be adjusted to fit within the current problem bounds.
3. It is recommended to use
problem.addMipSol instead of
problem.loadMipSol.
problem.addMipSol can be called both before a solve, to load a starting solution, and during a MIP solve, to load new solutions within callbacks.
problem.addMipSol also allows for loading of infeasible or partial solutions and comes with a callback to check the status of loaded solutions.
4. This function cannot be called while the current problem is being solved or when it is in an interrupted state. Use
problem.postSolve to restore the problem to a non-solving state.
