IRV occasionally is known as Ware's method right after its inventor, American William Robert Ware. When the single transferable vote (STV) system is placed on one-winner election, it gets IRV; the government of Eire has known as IRV "proportional illustration" based on The reality that the exact same ballot kind is utilized to elect its president by IRV and parliamentary seats by STV, but IRV is a winner-take-all election system.
