Hi,
I am using following code to solve an MINLP. I have two questions.
- How can I suppress solver output?
- I am using loginterval to increase the interval in which GAMS outputs the progress. But it doesn’t work. Below is the code and the command line output.
MODEL DP_loc_dep /eq1,eq2_loc_dep_1,eq3,eq3_1,eq4,eq4_1,capCon1,capCon2,alphaEqD,P1eqD,P2eqD,P3eqD,P4eqD, total_profit_DP/;
option
MINLP =SBB
limrow = 0
limcol = 0
reslim = 3600
optcr = 0.0
;
DP_loc_dep.nodlim = 1000;
DP_loc_dep.optfile = 1;
$onecho >SBB.opt
loginterval 100
loglevel 2
$offecho
solve DP_loc_dep using minlp maximizing obj;
My output is like below
** Optimal solution. Reduced gradient less than tolerance.
Root node solved locally optimal.
Resetting optcr to 1.0e-09
