Function GMP::Solution::GetBestBound(GMP, solution)

GMP::Solution::GetBestBound

The function GMP::Solution::GetBestBound returns the the best known bound on a solution.

GMP::Solution::GetBestBound(
     GMP,            ! (input) a generated mathematical program
     solution        ! (input) a solution
     )

Arguments

GMP

An element in AllGeneratedMathematicalPrograms.

solution

An integer scalar reference to a solution.

Return Value

In case of success, the best known bound. Otherwise it returns UNDF.

Note

  • This function can be used for GMPs with model type MIP, MIQP or MIQCP.

  • This function can also be used for GMPs solved with BARON, regardless of the model type.

  • This function can also be used for GMPs with model type QP that are solved with CPLEX, if the CPLEX option Solution Target is set to ‘Search for global optimum’.

  • This function can also be used for GMPs with model type QP or QCP that are solved with Gurobi 9.0 or higher, if the Gurobi option Nonconvex Strategy is set to ‘Translate’.
