WebOct 8, 2014 · The normal pattern for proving a greedy algorithm optimal is to (1) posit a case where greedy doesn't produce an optimal result; (2) look at the first place where its solution and the optimal solution diverge; and (3) prove that that place can't exist. Proof by contradiction. – Sneftel. WebGreedy algorithms take all of the data in a particular problem, and then set a rule for which elements to add to the solution at each step of the algorithm.
