Hi everyone,
i'm having a problem to get results for my optimization problem that i
run through NEOS.
When i look at the result, i can see that the solver find the optimal
solution, because it's the same objectif value that i get from another
solver that finished with "optimal", but it ends on a "Couenne finished.
No feasible solution found.".
here is the text from the solver where i can see that "optimal value":
"Clp0006I 7269 Obj 831436.86
Clp0000I Optimal - objective value 831436.86
Clp0032I Optimal objective 831436.862 - 7269 iterations time 0.522,
Presolve 0.
08
Clp0006I 0 Obj 831436.86 Primal inf 161.58395 (12)
Clp0006I 4 Obj 831436.86
Clp0000I Optimal - objective value 831436.86
NLP0014I 2 TIME 0 0 0.035995
Clp0000I Optimal - objective value 831436.86
Cbc0020I Exiting on maximum time"
but the solver ends with that message:
"**** SOLVER STATUS 3 Resource Interrupt
**** MODEL STATUS 14 No Solution Returned
**** OBJECTIVE VALUE NA "
So i wanted to how can i make the solver stops when it reach this
"Optimal - objective value"??
Thank you very much
Abdel
