* pre-root heuristic that tries some trivial (but often feasibile) solutions: all variables at their upper bounds, all
22
* variables at their lower bounds, all variables zero, all variables at the bound with the fewer locks. This will,
23
* e.g., find a start solution for all pure set covering or set packing problems.
