Comparison of three greedy algorithms for the MSSP using a toy example. A simulated graph G representing the paralogy relationships between 14 genes serves as input to each algorithm considered: GRAND, GMAX, GMIN. The final stable set of genes as well as the resulting graphs after two initial iterations are shown. Each iteration of GRAND consists of the removal of a random vertex (gene) whereas GMAX removes a vertex of maximum degree. This is repeated until no edges remain and the resulting set of genes is stable. GMIN selects a vertex of minimum degree to retain during each iteration and all adjacent vertices are removed. The process is repeated until G becomes empty and the retained vertices form a stable set.
