Greedy technique algorithm

WebNov 1, 2013 · Greedy algorithms constitute an apparently simple algorithm design technique, but its learning goals are not simple to achieve. We present a didactic method aimed at promoting active learning of greedy algorithms. The method is focused on the concept of selection function, and is based on explicit learning goals. WebAdd a comment. 2. A greedy algorithm will make a locally optimal choice at each step in the process hoping that this will result in a globally optimal solution, where as an exhaustive search will look at all possible solutions and pick the most optimal one. The greedy algorithm will run more quickly than the exhaustive one but the greedy ...
