solver:terminating_the_optimization_after_the_first_feasible_solution

Q: * Which GAMS or Cplex option can I use to make the solver stop quickly once a feasible solution has been found?*

On the GAMS level you can set `optcr`

and `optca`

to large numbers. If the bound and the value are on opposite sides of zero, this might result in larger values than one for `optcr`

. For setting `optca`

large enough you need some idea about the range of objective values. In GAMS/CPLEX there is also an option called `intsollim`

. Setting `intsollim`

to 1 will terminate the optimization after the first feasible integer solution.
