(Upper-left) Evolution of the frequencies of the ESS and the invader strategy starting from and respectively. (Upper-right) Evolution of the ESS and the invader strategy starting from and and ending up with the latter evolving to the former. (Lower) Evolution of the adaptive landscape and the two strategies: (i.e., before the invasion happens), is the global maximum; (i.e., the invasion happens), the adaptive landscape is elevated with still being the global maximum and being the global minimum; , the invader strategy climbs up with the adaptive landscape going down; , the invader strategy coincides with and reaches the top of the adaptive landscape, which falls back to the state before the invasion happens. Parameters: , , and .
