assortative matching and multiple production cycles to investigate which evolutionarily stable (EE) monomorphic population it … to (1 + b)/2 from 1/2 in pure random matching case. As the assortative index b rises, the basin of attraction of the EE H …-type solution rises. When the assortative matching is perfect (b = 1), in the Stag-Hunt game version (0 < e < ½), the monomorphic NH …
