ACE: Basic Framework + Population Dynamics This section is devoted to describe population dynamics. , and through the results of our previous experiments. 1. Schematic Description Threshold Response Functions The population dynamics follows the scheme as shown in figure 10.

2. ; 00 u The graphics show that the average entropy decreases when the number of foragers increases. This was also an expected result, because more patrollers mean more exploration· and thus higher levels of entropy. Obviously, the higher the ratio of foragers, the lower the level of entropy. lso when the population size increases. More agents means more patrollers which, in tum, means more exploratory searches. A low number of agents (approximately a population size below 20 agents) should be avoided because it may lead to erratic behaviors, due to the problem's degree of difficulty and the low number of available agents to solve it.
