by predators by charging through an aggregation of prey. However,
it has been noticed that variations exist in the geometric
shape of the charging front; in addition, distinct differences
arise between the shapes depending on the particulars of the feeding strategy. For example, each member of a dolphin
foraging group must contribute to the hunt and will only be
able to eat what it catches. On the other hand, some lions earn
a "free lunch" by feigning help and later feasting on the prey
caught by the more skilled hunters in the foraging group. We
model the charging front of the predators as a curve moving
through a prey density modeled as a reaction-diffusion process
and we optimize the shape of the charging front in both the
free lunch and no-free-lunch cases. These different situations
are simulated under a number of varied types of predator-prey
interaction models, and connections are made to multi-agent
robot systems
