•Present a deterministic approximation algorithm for submodular maximization with a curvature parameter α.•Generalize the previous deterministic 0.5008-approximation due to Buchbinder et al., achieving an identical ratio of 0.5008 when α=1.•Achieve a ratio of 1 for α=0 for which the function is actu...
