Question
Which of the following properties must a problem exhibit
to be solvable by a greedy algorithm?Solution
Greedy algorithms work by making locally optimal choices at each step with the hope that these choices will lead to a globally optimal solution. This requires two properties:   1. Greedy Choice Property: A globally optimal solution can be arrived at by making a locally optimal (greedy) choice.   2. Optimal Substructure: An optimal solution to the problem contains optimal solutions to its subproblems.
