Greedy Algorithm Characteristics
- The greedy algorithm does not always lead to the globally optimum solution.
- A greedy algorithm is a type of algorithm that makes the locally optimal choice at each step with the hope of finding a global optimum solution.
- The main characteristic of a greedy algorithm is that it makes the optimal choice at each step as it attempts to find the overall optimal solution.
Domain and Downsides
