- | 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 solution. | + | On the GAMS level you can set ''optcr'' and ''optca'' to large numbers.
