int GRBreset ( GRBmodel *model,
    int clearall )

Reset the model to an unsolved state, discarding any previously computed solution information.

Return value:

A non-zero return value indicates that a problem occurred while resetting the model. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.


model: The model to reset.

clearall: Should additional information such as MIP starts, variable hints, branching priorities, lazy flags, and partition information be cleared.

Example usage:

  error = GRBreset(model, 0);
