We give a (1-1/e)-approximation algorithm for the max-profit generalized assignment problem (Max-GAP) with fixed profits when the profit (but not necessarily the size) of every item is independent from the bin it is assigned to. The previously best-known approximation ratio for this problem was 1 2
