MIPRELSTOP

Branch and Bound: This determines whether or not the global search will terminate. Essentially it will stop if:
|MIPOBJVAL - BESTBOUND| Maths/leq.png

MIPRELSTOP x BESTBOUND
where MIPOBJVAL is the value of the best solution's objective function and BESTBOUND is the current best solution bound. For example, to stop the global search when a MIP solution has been found and the Optimizer can guarantee it is within 5% of the optimal solution, set MIPRELSTOP to 0.05.

Description	Branch and Bound: This determines whether or not the global search will terminate. Essentially it will stop if: \|MIPOBJVAL - BESTBOUND\| MIPRELSTOP x BESTBOUND where MIPOBJVAL is the value of the best solution's objective function and BESTBOUND is the current best solution bound. For example, to stop the global search when a MIP solution has been found and the Optimizer can guarantee it is within 5% of the optimal solution, set MIPRELSTOP to 0.05.
