WebDynamic Programming on Trees Fact: Many graph optimization problems are NP-Hard Fact: The same graph optimization problems are in P on trees. Why? A signi cant reason: DP algorithm based on decomposability Powerful methodology for graph algorithms via a formal notion of decomposability called treewidth (beyond the scope of this class)
WebDynamic Programming requires: 1. Problem divided into overlapping sub-problems 2. Sub-problem can be represented by a table 3. Principle of optimality, recursive relation between smaller and larger problems Compared to a brute force recursive algorithm that could run exponential, the dynamic programming algorithm runs typically in quadratic time.
