We restate the theoretical statements and the algorithms here for completeness and convenience. Given a normalized monotone submodular function f:2 V! The objective aims to find the partition such that the minimum-valued block in the partition is maximized. For a ground set V and its elements (v1,v2,...,v n) coming in an arbitrary streaming order, the output solution of Alg. 1 has The output solution of Alg. 2 has We construct a set cover function as the tight example for Corollary 1. We illustrate the set cover function graphically in Figure 1. The circles are the areas to cover for the set cover function and the green inner circles and the red triangles are elements in the ground set (the outer yellow circles are not elements). The inner circles (green) largely overlap with the outer circles (yellow).
