BP maximization problem has many applications in machine learning and data science. It can be described as maximizing the sum of a suBmodular function and a suPermodular function (BP) under some constraints, where both functions are nonnegative and monotonic. In this paper, we consider two online cases. The first is a BP maximization problem subject to a uniform matroid constraint when the items arrive one-by-one, for which we offer an online algorithm with constant competitive ratio. The second is a BP maximization problem subject to a partition matroid constraint where each part of the partition arrives in a random order, for which we present two approximation algorithms of both constant competitive ratios, where one is randomized and the other is deterministic.
