Comments on the paper: “On the properties of equidifferent OWA operator” by Xinwang Liu

In this communication, we will point out an interesting correspondence between a recent paper “On the properties of equidifferent OWA operator” [International Journal of Approximate Reasoning, in press, ] by Liu, and an earlier result “On obtaining minimal variability OWA operator weights” [Fuzzy Sets and Systems 136 (2003) 203–215] by Fullér and Majlender.
