Function GMP::Solution::IsInteger(GMP, solution, tolerance)

GMP::Solution::IsInteger

The function GMP::Solution::IsInteger checks whether the solution for a generated mathematical program is an integer solution.

GMP::Solution::IsInteger(
     GMP,            ! (input) a generated mathematical program
     solution,       ! (input) a solution
     [tolerance]     ! (optional) a tolerance
     )

Arguments

GMP

An element in the set AllGeneratedMathematicalPrograms.

solution

An integer scalar reference to a solution.

tolerance

A numerical value. The default is 0.

Return Value

The function returns 1 if the solution is integer, and 0 otherwise.

Note

If the mathematical program contains Special Ordered Sets (SOS) then this function also checks whether the solution satisfies them. If one of the SOS sets is violated then this function returns 0.
