GMP::Solver::FreeEnvironmentcan be used to free a solver environment. By using the procedure
GMP::Solver::InitializeEnvironmentyou can initialize a solver environment; by using this procedure you can free it again.
Normally AIMMS initializes solver environments at startup and frees them when it is closed. The procodures
GMP::Solver::FreeEnvironmentcan be used to initialize and free a solver environment multiple times inside one AIMMS sesstion. Both procedures are typically used for solvers running on a remote server or a cloud system.
GMP::Solver::FreeEnvironment( solver ! (input) a solver )
The procedure returns 1 on success, or 0 otherwise.
- This procedure can be used in combination with a normal solve statement.
- This procedure is only supported by GUROBI.
- This procedure cannot be called inside a solver callback procedure.
- This procedure cannot be called if one of the solver sessions is asynchronous executing.
