Equilibrium locations of location game
Description
Function finds the equilibrium locations of a location game, similar to a hotelling game. Clients choose the location closest to them.
Usage
lgsolve(edgeMatrix, coordMatrix, nPlayers = 2, demandLoc)
Arguments
edgeMatrix |
A square matrix consisting of zeros and ones. Has to be zero on the diagonals |
coordMatrix |
A data frame containing the x and y coordinates of each network vertex |
nPlayers |
Number of players in the location game. Default is set to 2, which is the only number of players supported right now. |
demandLoc |
A vector containing the demand or profit at each vertex of the network |
Value
A list with two components. A matrix with zeros and ones, where a one symbolizes a equilibrium location. The row index denotes the location of player 1, and the column index the location chosen by player 2. The second entry is a summary of all equilibrium locations and the payoffs for player 1 and 2.
Examples
edgeMatrix <- matrix(0, nrow = 6, ncol = 6)
edgeMatrix[,1] <- c(0,1,0,0,0,0)
edgeMatrix[,2] <- c(1,0,1,0,1,0)
edgeMatrix[,3] <- c(0,1,0,0,0,0)
edgeMatrix[,4] <- c(0,0,0,0,1,0)
edgeMatrix[,5] <- c(0,1,0,1,0,1)
edgeMatrix[,6] <- c(0,0,0,0,1,0)
coordMatrix <- matrix(c(0,3,0,2,0,1,1,3,1,2,1,1), nrow = 6, ncol = 2, byrow = TRUE)
demandLoc <- c(100, 100, 100, 100, 100, 100)
