(There is also an easy O (1) algorithm but the idea here is to illustrate dynamic programming.) The idea: Compute thesolutionsto thesubsub-problems once and store the solutions in a table, so that they can be reused (repeatedly) later. Break up a problem into sub-problems, solve each sub-problem independently, and combine solution to sub-problems to form solution to original problem. To me, the practice of 2.1 and understanding of 4 were the tipping point. After that, DP became really easy for me and a weapon to solve many problems, that even have other solutions (usually greedy, which is harder to come up with) 481 Steps1-3 form the basisof a dynamic-programming solution to a problem. Tree DP Example Problem: given a tree, color nodes black as many as possible without coloring two adjacent nodes Subproblems: – First, we arbitrarily decide the root node r – B v: the optimal solution for a subtree having v as the root, where we color v black – W v: the optimal solution for a subtree having v as the root, where we don’t color v – Answer is max{B Try some practice problems!
