Chicken (game) respectively. The line in graph on the left shows the optimum probability of playing the escalated strategy for player Y as a function of "x". The line in the second graph shows the optimum probability of playing the escalated strategy for player X as a function of "y" (the axes have not been rotated, so the dependent variable is plotted on the abscissa, and the independent variable is plotted on the ordinate). The Nash equilibria are where the players' correspondences agree, i.e., cross. These are shown with points in the right hand graph. The best response mappings agree (i.e., cross)
Heawood graph has automorphisms that take any vertex to any other vertex and any edge to any other edge. More strongly, the Heawood graph is 4-arc-transitive. According to the Foster census, the Heawood graph, referenced as F014A, is the only cubic symmetric graph on 14 vertices. It has book thickness 3 and queue number 2. The characteristic polynomial of the Heawood graph is formula_1. It is the only graph with this characteristic polynomial, making it a graph determined by its spectrum. Heawood graph In the mathematical field of graph theory, the Heawood graph is an undirected graph with 14 vertices and 21
