Developing a genetic algortihm

We should take care when designing the entity which would evolve in the genetic algorithm as its representation would constrict our domain. For exampe, you can't make Skynet with entity which is represented by two bits. The looseness of an entity representation is actually the size of our domain. The representation of entity makes the corners from which our evolution can not go further. So, the entity is put into the unmerciful hands of a fitness function.
