PDF We consider an online decision problem over a discrete space in which the loss function is submodular. We give algorithms which are computationally efficient and are Hannan-consistent in For general submodular functions, this Fujishige-Wolfe minimum norm algorithm seems to have the best empirical performance. Despite its good practical performance, very little is known about WolfeвЂ™s minimum norm algorithm theoretically.

algorithms for minimizing a submodular set function can be adopted to minimize a submodular function over a bounded integer lattice (Fujishige,2005).
