Branch-and-Bound

aka Brute Force's Wise and Sensible Sister. A bit younger than Backtracking, but able to pick up on his technique, doesn't go headlong down a path. At every junction, notes the likeliness of a good path (may even go back to a junction which has a slightly better promise of a path!) and goes down each to the next junction. Meticulous, has the best eyes amongst the siblings, and sometimes comes with the best answer before either of her brothers. Will definitely know that it is best before anyone else does, and is often annoyed if Greedy Technique gloats about being there first.
