Go to the documentation of this file.
21 * This heuristic tries to find solutions by taking the LP or NLP, rounding solution values, fixing the variables to the
22 * rounded values and then changing some of the values.To determine which variable is changed we give each variable a
23 * ranking dependent on its dualvalue. We work with a transformed problem that is always feasible and has objective = 0
24 * iff the original problem is also feasible. Thus we cannot expect to find really good solutions.
