Technique Application: Escaping Local Minima
While it is technically possible that given enough time, everyone would invent every technique, it is possible for people to get stuck in local minimum.
A player can get stuck around a sub-optimal solution because it requires too much bizarre experimentation to move to the optimal solution.
If she is frustrated with the search and not making any progress, then it can be helpful to use technique to place her on a completely different spot on in the space.
It is important to emphasize to the player that the technique is just a new center of exploration, not the actual optimal solution.
