GRBModel::reset()

void reset ( int clearall=0 )

Reset the model to an unsolved state, discarding any previously computed solution information. Note that, due to our lazy update approach, the change won't actually take effect until you update the model (using GRBModel::update), optimize the model (using GRBModel::optimize), or write the model to disk (using GRBModel::write).

clearall (optional): 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). The default value of 0 just discards the solution.
