The dynamics of foraging are characterized by learning and food choice [21, 24]. Foragers move through the environment and when they encounter resource items, the food choice algorithm determines whether any are consumed (Eq. 1). Foragers start out exploring various unknown resources (via P E and/or P S), and as they gain experience about rewards, personal information tends to become more dominant in their food choices. Personal experience is updated after consumption events and includes a ir, the assessment of rewards (Eq. 6) and the increment of skill (Eq. 4) which in turn increases the reward obtained (Eq. 5). Due to consumption of many resources, the expectation of the environment a ie will increase, increasing the fraction of resources for which a ie is greater than an expected reward a ir. This increases selectivity towards resources with high expected reward a ir, and can lead to reduced food intake (i.e. a forager’s stomach is no longer full at digestion). At this point the expectation of the environment a ie decreases again.
