Equilibrium point	Eigenvalue symbol	Stability of equilibrium point
E9 (0, 0, 0, 0)	(+, X, X, X)	Instability point
E10 (1, 0, 0, 0)	(−, +, X, X)	Instability point
E11 (0, 1, 0, 0)	(+, X, X, X)	Instability point
E12 (0, 0, 1, 0)	(+, X, X, X)	Instability point
E13 (1, 1, 0, 0)	(X,−, X, +V)	Instability point
E14 (1, 0, 1, 0)	(X, +, +, +)	Instability point
E15 (0, 1, 1, 0)	(+, X, X, X)	Instability point
E16 (1, 1, 1, 0)	(−, −, −, −)	ESS in condition (c)

Note: X means uncertain of symbol, and ESS means the evolutionarily stable strategy.
