Greedy Algorithms Overview

The algorithm must always produce the global best result

The algorithm must work in a top-down approach

The problem must have an optimal substructure

The optimal solution can be found by choosing the best choice at each step without reconsidering previous steps (correct)

It reverses earlier decisions if they are wrong

It selects the best option available at the moment (correct)

It always finds the global best result

It works in a bottom-up approach

The optimal overall solution must correspond to the optimal solution of its subproblems (correct)

The algorithm must always produce the global best result

The problem must have the greedy choice property

The algorithm must work in a bottom-up approach
