It is required to place in order n books B₁, B2, ..., Bn on a library shelf in such a way that readers searching from left to right waste as little time as possible on average. Assuming that each reader requires book B, with probability pi, find the ordering of the books which minimizes P(Tk) for all k, where T is the (random) number of titles examined by a reader before discovery of the required book.
