Research Type Experimental We consider five different OSM problems: two influence maximization problems, over the ZKC (Zachary 1977) and Epinions (Richardson, Agrawal, and Domingos 2003) graphs, respectively, a facility location problem over the Movie Lens dataset (Harper and Konstan 2015), a team formation, and a weighted cov-....A comparison between the two versions of RAOCO (OGA and OMA) with the three competitors is shown in Table 1. We observe that both OGA and OMA significantly outperform competitors, with the exception of Movie Lens, where Tabular Greedy does better. OMA is almost always better than OGA.
