WebJan 26, 2024 · Introducing Dynamic Programming via backward recursion also seems to be the status quo in the textbooks. However, these problems (for example: shortest path problems) can also be solved via forward recursion. Why is it claimed then, that "backward recursion" usually performs faster than forward recursion?
