### GRBreset

 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.

Arguments:

model: The model to reset.

clearall: A value of 1 discards additional information that affects the solution process but not the actual model (currently MIP starts, variable hints, branching priorities, lazy flags, and partition information). Pass 0 to just discard the solution.

Example usage:

  error = GRBreset(model, 0);
