Greedy Is Optimal for Online Restricted Assignment and Smart Grid Scheduling for Unit Size Jobs,hat (i) the two instances admit the same optimal offline schedule; (ii) the cost of the online algorithm is at least that of the greedy algorithm on the respective job instance. With these properties, we can show that the competitive ratio of the greedy algorithm is the smallest possible.

We also provide a 3-approximation algorithm and an inapproximability ratio of . for the case of unrelated machines.

Terrain-Like Graphs: PTASs for Guarding Weakly-Visible Polygons and Terrains,om its vertices. We also present PTASs for continuously guarding the boundary of a WV-polygon or WV-terrain, either from its vertices, or, for a WV-terrain, from arbitrary points on the terrain. Finally, we compare between terrain-like graphs and . graphs, and also observe that both families admit PTASs for ..

Fair Coresets and Streaming Algorithms for Fair ,-means,se of two colors (and exact balances). Furthermore, we extend techniques due to Chierichetti et al.?[.] to obtain an approximation algorithm for .-means, which leads to a constant factor algorithm in the streaming model when combined with the coreset.
