Uses Design Technique

Connects an algorithm to the design technique it is built on, such as dynamic programming, divide and conquer, backtracking or a greedy method. The inverse reading, Technique Used By, names the same link from the technique toward each algorithm grouped under it. This relation gives the design technique already recorded as an enum fact on each algorithm a durable entity identity; it does not replace that enum fact, which keeps classifying every algorithm exactly as before, and a compound label such as heuristic or approximation is linked to each of the named techniques.
