static |
helper method that sets up and solves the sub-SCIP for removing infinite values from solutions
scip | SCIP data structure |
subscip | SCIP data structure of sub-SCIP |
origvars | original problem variables of main SCIP |
norigvars | number of original problem variables of main SCIP |
solvals | array with solution values of variables; infinite ones are replaced |
success | pointer to store if removing infinite values was successful |
