Websubstructure. One of the optimal solutions makes a cut at 3cm, giving two subproblems of We need to solve both optimally. 3cm rod is no cuts. As we saw above, the optimal solution for a 4cm rod involves cutting into 2 pieces, each of length 2cm. These subproblem optimal solutions are then used in the solution to the problem of a 7cm rod. WebFinding the shortest path in a graph using optimal substructure; a straight line indicates a single edge; a wavy line indicates a shortest path between the two vertices it connects (among other paths, not shown, sharing the same two vertices); the bold line is the overall shortest path from start to goal.
