How to go from a smaller solution to a larger solution. A common idea in DP on Trees is to have the sub-problems represent answers for subtrees (+ some state, we’ll see what this means in a bit).
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.
