Greedy algorithm general method

WebA greedy algorithm refers to any algorithm employed to solve an optimization problem where the algorithm proceeds by making a locally optimal choice (that is a greedy choice) in the hope that it will result in a globally optimal solution. In the above example, our greedy choice was taking the currency notes with the highest denomination. WebThis method of solving a solution is referred to as dynamic programming. Such problems involve repeatedly calculating the value of the same subproblems to find the optimum solution. Dynamic Programming Example. ... However, greedy algorithms look for locally optimum solutions or in other words, a greedy choice, in the hopes of finding a global ...
