WebMar 30, 2024 · The greedy algorithm can be applied in many contexts, including scheduling, graph theory, and dynamic programming. Greedy Algorithm is defined as a method for solving optimization problems by taking decisions that result in the most evident and immediate benefit irrespective of the final outcome. In a greedy Algorithm, we make whatever choice seems best at the moment in the hope that it will lead to global optimal solution. In Dynamic Programming we make decision at … See more In Greedy Method, sometimes there is no such guarantee of getting Optimal Solution. It is guaranteed that Dynamic Programming will … See more
