- Procedure GMP::Solver::FreeEnvironment(solver)
GMP::Solver::FreeEnvironment
GMP::Solver::FreeEnvironment
can be used to free a
solver environment. By using the procedure
GMP::Solver::InitializeEnvironment
you can initialize a solver
environment; by using this procedure you can free it again.GMP::Solver::InitializeEnvironment
and
GMP::Solver::FreeEnvironment
can 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
)
Arguments
- solver
An element in the set
AllSolvers
.
Return Value
The procedure returns 1 on success, or 0 otherwise.
Note
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.
Example
Assume that ‘MIPSolver’ is an element parameter with range
AllSolvers
and ‘myGMP’ is an element parameter with rangeAllGeneratedMathematicalPrograms
.MIPSolver := 'Gurobi 10.0'; ! First solve using normal solve statement. GMP::Solver::InitializeEnvironment( MIPSolver ); solve MP1; GMP::Solver::FreeEnvironment( MIPSolver ); ! Second solve using GMP solve. GMP::Solver::InitializeEnvironment( MIPSolver ); mgGMP := GMP::Instance::Generate( MP2 ); GMP::Instance::Solve( myGMP ); GMP::Solver::FreeEnvironment( MIPSolver );
