 * @brief  trivial primal heuristic
 * @author Timo Berthold
 *
 * pre-root heuristic that tries some trivial (but often feasibile) solutions: all variables at their upper bounds, all
 * variables at their lower bounds, all variables zero, all variables at the bound with the fewer locks. This will,
 * e.g., find a start solution for all pure set covering or set packing problems.
