Figure 7. Different behaviors with an imperfect filter between environments.
(A) The populations of 
(black) and 
(gray) form a stable oscillation as the environments cycle between 
and 
. The transition probabilities are presented 
in the order of 
, 
, 
, and 
. For 
the transition probabilities are 
and for 
they are 
. (B) 
(black) drives 
(gray) extinct. For 
the transition probabilities are the optimal set using perfect filters 
and for 
they are 
. (C) 
(black) and 
(gray) monotonically approach the same frequency in the population. For 
the transition probabilities are 
and for 
they are the optimal set when perfect filters are used 
. (D) 
(black) decreases in frequency for five rounds before changing direction and driving 
(gray) extinct. The transition probabilities for 
are 
and for 
they are 
.
