Abstract

This article deals with the design of effective algorithms for solving combinatorial problems of the type "How many different ways can something be done?". We will demonstrate the solution procedure on three seemingly completely different problems: how many different ways can we get from one point of a road network to another, how many different ways can we pave a path using tiles of specified dimensions, and how many different binary trees of a given size exist. As we will see, the basic principle for solving all these problems will be the same—we will use the method of dynamic programming.
