Historical Relative Performance Index Over Interconnectedness of Badminton Athletes

The paper proposes the Historical Relative Performance Index in order to quantitatively extract information in the scores hit in the sets of head-to-head game in badminton tournaments. The index is treated as the weights of the directed networks built between competing athletes. The paper also proposes the way to build the fully connected network based on the empirically found network in order to have relative index between athletes that have never nor will be met in series of games. Some further directions as well as implementation to small amount of data is described for advanced analysis.
