The mathematical program suffix
.CallbackTimecontains the name of the AIMMS procedure to be called after a certain number of seconds have elapsed.
The value of the
.CallbackTimesuffix is an element in the set of
AllProceduresand the default is the empty element
CallbackTimecallback procedure is supported by CPLEX, GUROBI, CBC, XA, CP OPTIMIZER, CONOPT, KNITRO, SNOPT and IPOPT.
The number of (elapsed) seconds is determined by the general solvers option
Progress Time Interval. This option also specifies the interval for updating the Progress Window during a solve. As a consequence, the information passed to this callback procedure will be the same as the information displayed in the Progress Window (except for small differences for the solving time).
The time callback will be called less often if CPLEX uses dynamic search as the MIP Search Strategy instead of branch-and-cut. In that case the interval between two successive calls might sometimes be larger than the interval as specified by the option
Progress Time Interval.
