TRIANA, Juan Gabriel  and  ROLDAN, Diego Gerardo. A PERSECUTION TECHNIQUE USING UNCONVENTIONAL MIMICRY. rev.udcaactual.divulg.cient. [online]. 2013, vol.16, n.2, pp.519-523. ISSN 0123-4226.

In nature it is very common to find situations where two or more species interact in a specific way, being one the hunter and the other one the prey. This interaction between species is designated as hunting. There are many mathematical models that describe this behavior between species, considering even other species in the dynamics. Usually the direction of the hunters velocity vector equals the direction of the preys velocity vector, at speeds that may be or not constant. This is the usual technique of persecution. But the main disadvantage of this technique is that the prey can sense when the hunter approaches, which provides an advantage of valuable seconds to escape, which means a problem, especially for those hunters which do not develop adequate speed to catch the possible victim. This paper describes a special technique that uses an additional element, which can be considered as mimicry, since the idea is to fool the prey, to believe in some way that approach never occurs. In this technique effects such as change in the hunters size and shadows, between others are despised. Camouflage movement equations are deduced and in some special cases simulations of these equations are performed. These equations are easy to simulate and the results suggest that in some cases this strategy is better than the classical persecution techniques.
