GRBsetintparam

GRBsetintparam

int	GRBsetintparam(	GRBenv	*env,
		const char	*paramname,
		int	newvalue )

Modify the value of an integer-valued parameter.

Return value:

A non-zero return value indicates that a problem occurred while modifying the parameter. Refer to theError Codetable for a list of possible return values. Details on the error can be obtained by callingGRBgeterrormsg.

Arguments:

env: The environment whose parameter value is being modified.

paramname: The name of the parameter. Please consult theparameter sectionfor a complete list of Gurobi parameters, including descriptions of their purposes and their minimum, maximum, and default values.

newvalue: The desired new value of the parameter.

Important note:

Note that a model gets its own copy of the environment when it is created. Changes to the original environment have no effect on the copy. UseGRBgetenvto retrieve the environment associated with a model if you would like a parameter change to affect that model.

Example usage:

error = GRBsetintparam(GRBgetenv(model), "SolutionLimit", 5);
