Thus the forager’s expectation of the environment a ie tends to equilibrate on a value in relation to values of a ir, such that the intake of resource items is close to the maximum of 20. This ensures that the forager is eating selectively but still eating close to the maximal number of resource items within each digestion cycle (DIGESTONTIME). The ratio of a ir to a ie is therefore similar across simulation types, irrespective of how fast a ir increases due to differences in skill development time.
