Detailed Description

GEPChromosome class - implements genotype as a Gene Expression Programming chromosome.

This representation consists of one or more genes, each consisting of two main parts and an optional third component. The first part is called the Head. It has a size specified by the user and may contain any primitive. The second part is called the Tail. It may contain only terminals and has a fixed size (depending on the maximum arity of the primitive set and the head length). These two properties, along with the expression procedure, guarantee that every GEP chromosome encodes a valid expression. The optional third part is called the "Dc domain". It contains the values of random constants and has the same size as the Tail. If used, a constant placeholder primitive "?" is added to the primitive set. GEPChromosome inherits a fixed-size vector of Node objects. Each node points to a Primitive object. Nodes in tree are aligned in a breadth-first notation. Being fixed-size and breadth-first-expressed, this means that non-coding neutral node regions can exist in any given individual. Some primitives are shared among all the trees, but some (such as ERC primitives) belong to a single GEPChromosome.
