getCriticalCoalitionsOfPlayer: Compute critical coalitions of a player for simple games

Description

getCriticalCoalitionsOfPlayer identifies all coalitions for one player in which that player is critical (within a simple game). These coalitions are characterized by the circumstance that without this player the other players generate no value (then also called a losing coalition) - therefore this player is also described as a critical player.

Usage

getCriticalCoalitionsOfPlayer(player, v)

Arguments

player

represents the observed player

v

Numeric vector of length 2^n - 1 representing the values of the coalitions of a TU game with n players

Value

A data frame containing all minimal winning coalitions for one special player
