plotcoresets {TUGLab}R Documentation

Plot multiple core sets

Description

Given multiple games with two, three or four players, this function draws in a single plot their projected core sets and sets of imputations.

Usage

plotcoresets(games, binary = FALSE, imputations = TRUE)

Arguments

games

A matrix in which each row is a characteristic function.

binary

A logical value. By default, binary=FALSE. Should be set to TRUE if the characteristic functions in games are introduced in binary order instead of lexicographic order.

imputations

A logical value. By default, imputations=TRUE. When set to imputations=FALSE, the sets of imputations are not drawn.

Details

The core of a game v\in G^N is the set of all its stable imputations:

C(v)=\{x\in\mathbb{R}^n : x(N)=v(N), x(S)\ge v(S)\ \forall S \in 2^N\},

where x(S)=\sum_{i\in S} x_i.

Value

A plot of the given core sets.

Examples

# Plotting the core and the least core of a game:
v <- c(0,0,0,0,10,40,30,60,10,20,90,90,90,130,160)
vt <- leastcore(v)$vt
plotcoresets(games = rbind(v,vt), imputations = FALSE)
