How do you synthesize ranking information into a single most representative global ranking? This can be modeled as an optimization problem. There are a few possibilities for the objective. Related to the feedback arc set problem in directed graphs, its theoretical formulation is difficult to solve exactly. We will show simple heuristics and analyze them from the viewpoint of quality of approximation.
