In the binary minimax tree problem we are given non-negative weights W=(w"1,...,w"n). The task is to find a rooted binary tree T with n leaves and an assignment of the leaves to the weights such that the maximum over all leaves l of the weight of l plus the depth of l is minimized. We present an online algorithm for building an optimal binary minimax tree with integral weights that runs in O(nlogn/loglogn) time using exponential search trees. Moreover, we show that no online algorithm computing an optimal minimax tree exists if we allow non-integral real weights.
