Q: Japan's Chikyu Hakken is trying to reach this region, and n-waves travel along its upper boundary. Post-perovskite forms in the bottommost part of this region, the D double prime layer. P-waves slow down and S-waves disappear past the bottom of this region, and its top features a P-wave velocity jump from approximately seven to approximately eight kilometers per second. The low velocity zone of the asthenosphere is found in the upper part of this region. It is sandwiched between the Gutenburg discontinuity and the Moho, and this layer's namesake plumes form hotspots. For 10 points, name this layer of the earth between the crust and the core.

Q: Procedures of this type can provide polynomial time solutions to such problems as finding optimal places to insert line breaks in a body of text, finding the largest common substring of two strings, and the integer knapsack problem. They can provide vast improvements over exhaustive search algorithms by caching the answers to intermediate computations. FTP, name this type of algorithm that generally uses recurrence relations and the principle of optimality to solve optimization problems by first solving related subproblems, and which often works where greedy algorithms fail.
