Chapter 3

Chapter 3. The Greedy Method. The greedy method . Suppose that a problem can be solved by a sequence of decisions. The greedy method has that each decision is locally optimal. These locally optimal solutions will finally add up to a globally optimal solution.

Longest common subsequence

Longest common subsequence. Definition 1: Given a sequence X=x 1 x 2 ...x m , another sequence Z=z 1 z 2 ...z k is a subsequence of X if there exists a strictly increasing sequence i 1 i 2 ...i k of indices of X such that for all j=1,2,...k, we have x ij =z j .
