WebApr 3, 2024 · One way to teach greedy algorithms is to use examples that illustrate their advantages and disadvantages. You can show how greedy algorithms can solve problems like coin change,... WebInstead of considering multiple choices to solve a subproblem, greedy algorithms only consider a single subproblem, so they run extremely quickly { generally, linear or close-to-linear in the problem size. Unfortunately, greedy algorithms do not always give the optimal solution, but they frequently give good (approximate) solutions.
