WebNov 3, 2024 · The idea is that we will initially use the epsilon greedy strategy: We specify an exploration rate - epsilon, which we initially set to 1. This is the frequency of the steps we will do randomly. In the beginning, this rate should be the highest value because we know nothing about the importance of the Q table. This means that we have to do a ... WebThe greedy algorithms first started coming into the picture in the 1950s. The then scientists, Prim and Kruskal also achieved the optimization techniques for minimizing the costs of graphs during that decade. A few years later, in the 1970s, many American researchers proposed a recursive strategy for solving greedy problems.

WebJun 24, 2016 · Greedy algorithms usually involve a sequence of choices. The basic proof strategy is that we're going to try to prove that the algorithm never makes a bad choice. Greedy algorithms can't backtrack -- once they make a choice, they're committed and will never undo that choice -- so it's critical that they never make a bad choice.
