[Clp] status after solver a problem

[SALOMEHER at terra.es]

Hi,

But there is a function such clp->status(), It returns for example:
    1: optimal
    2: feasible
    3: unbound
    4: time limit exceeded

Thank you.

Hello Salomeher,

optimal: an optimal solution was found and proven
feasible: as feasible solution was found, but you don´t know if it is the optimal solution

unbound. you are askin to maximize somthing that doesn´t have a constraint the limits its maximal value (so its infinite ou unbounded). Your mathematical model isn´t right.
time limit exceed: the maximum time set to solver was reached.


The output file have in the first line the status of the optimization.

Best regards,
Jack

Hi,
What are the different status in Clp (optimal, feasible, unbound, time limit exceeded, ...)? And how do I know these after solving a problem?


Thank you.
