a new parameter to control to force MIPStart if the variables are feasible

CPLEX choose to use MIPStart or not accoring to the heuristic. But sometimes the user think MIPStart values as particular variables is the best way to solve the problem. So we’d like to request a new parameter to control to force MIPStart if the v...
