Dynamic programming on trees
WebDynamic Programming, in Trees question: why does dynamic programming work on trees? De nition G = (V,E). A set of nodes S ⊆V is a separator for G if G −S has at ≥2 connected components, that is, G −S is disconnected. S is a balanced if each connected component of G −S has ≤2 3 · V vertices. e.g., in trees, every vertex is a ... 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.

WebYou can solve it using Dynamic Programming . Consider an array dp [] which stores the answer for each of the vertex and its subtree. Now state of DP would be, dp [currentVertex] = max (sum of all children's dp [] , b [currentVertex] + sum of all vertices' dp [] whose greatGrandParent is currentVertex]) You need to build DP table using bottom-up ...
