網頁Let K be the set of terminal vertices, to compute answer to the problem we call DP at state ( K, r o o t) for all possible roots of Steiner Tree and take the minimum. To speed up DP, we use bitmasks to represent X in DP state. When X = 1, solution is trivial. We will use this as base case of the DP.
