Hi all.

I have a simple question about solving MINLP.

I gave all initial values of variables in MINLP including objective
variable and binary variables.

GAMS result was same with initial values and GAMS showed like below;
--------------------------------------------------------------------
DICOPT : Terminating.......
DICOPT : Stopped on NLP worsening

DICOPT : Best integer solution found : 99555.22
--------------------------------------------------------------------
the solution is exactly same with initials.

In this case, didn't solver calculate the objective? then did it show
initials as solution??
Because it cannot be same with the initials....

Please anwser my question if someone knows this situation.

Thanks all
