Fig. 5: Benchmark analysis of random graphs.

a 100-vertex random graphs with different edge densities (=1.7%, 19.6%, 39.8%, 60.5%, 78.5%, 98.9%). b Ground state solutions for graphs in a and the resulting max-cut values. c Results with various-density random graphs. Observed probability of obtaining a solution whose cut size is at least x% of the max-cut at ground state, as a function of edge density. The running graphs are random graphs with 100 vertices and various densities. Error bars indicate the standard deviations in multiple 100 runs
