Silverman's game : ウィキペディア英語版 | Silverman's game In game theory, Silverman's game is a zero sum game played on the unit square. It is named for David Silverman. It is played by two players on a given set ''S'' of positive real numbers. Before play starts, a threshold and penalty are chosen with and 1 < ''T'' < ∞ Each player chooses an element of ''S''. Without loss of generality, suppose player A plays ''x'' and player B plays ''y'', with ''x'' > ''y''. Then the payoff to A is 1 if 1 < ''x''/''y'' < ''T'' and if ''x''/''y'' > ''T''; equal numbers involve zero payoff. Thus each player seeks to choose the larger number, but there is a penalty of for choosing too large a number. ==References==
