Ranked Pairs

Main article: Ranked pairs

In 1987, he devised the voting system called "ranked pairs" (or the "Tideman method" or simply "RP"), which is a type of Condorcet method. It selects a single winner using votes that express a preference ranking.[1][2] Ranked pairs can also be used to create a sorted list of winners.

Other research

In 2000, Tideman developed the CPO-STV proportional voting method. Tideman also devised the independence of clones criterion which both of his methods satisfy. He is an associate of the Earth Rights Institute. His book Collective Decisions and Voting: The Potential for Public Choice was published by Ashgate Publishing in November 2006.[3]
