内容記述 | Power indices of weighted majority games are measures of the effects of parties on the voting in a council. Among the many kinds of power indices, Banzhaf index, Shapley-Shubik index and Deegan-Packel index have been studied well. For computing these power indices, dynamic programming algorithms had been proposed. The time complexities of these algorithms are O(n^2q), O(n^3q), and O(n^4q), respectively. We propose new algorithms for computing power indices, whose time complexities are O(nq), O(n^2q), and O(n^2q), respectively. | |||||||||
