WebIn many optimization algorithms a series of selections need to be made. A simple design technique for optimization problems is based on a greedy approach, that builds up a solution by selecting the best alternative in each step, until the entire solution is constructed. When applicable, this method can lead to very simple and e cient algorithms. WebJul 21, 2024 · An algorithm is said to be greedy if at every step it chooses a candidate and adds it to the solution set, without worrying about optimality, which is very clear in how …
