Other optimization techniques
There exist other types of optimization techniques that mimic nature as: genetic algorithms, swarn particle optimization, simulated annealing, ant intelligence... These techniques are not so constrained as the classical ones.

Gecko has developed a beatiful estrategy of confussing depredators in their attack, they surely attack the most prominent extreme, that seems the head, but is the tail.
Beatiful creature, even the elbows and knees are apparently the opposite.
