Hello,
I am using GAMS to invoke several solvers on a MISOCP.
I would like to retrieve the following information on the solution obtained within a certain time limit: the computational time required for finding the incumbent.
Is it possible to obtain this information without looking at the log file printed by the specific solver?
Thanks.
Claudio

Claudio,
Some GAMS solvers offer the functionality of a SolveTrace (or MIPTrace): https://www.gams.com/help/topic/gams.doc/solvers/advanced/index.html?cp=0_3_1_2#ADVANCED_USAGE_SOLVETRACE which give you information at what time (or node count) you have what solution and bound. The following solvers use MIPTrace: Cplex, Gurobi, SBB, and Xpress. SolveTrace is used by: AlphaECP, Antigone, Bonmin, Cbc, Couenne, GloMIQO, LocalSolver, SCIP, and Sulum.
Hope this helps,
