Detailed Description

Information about the set of categories used in a specific problem.

More fine grained data types are required for Strongly Typed Genetic Programming: i.e. not just double but possibly multiple categories (category_t) that are subset of a d_double domain_t. Categories avoid mixing 3 Km/h with 4 Kg (in simple cases there is only one category for each domain).

The src_problem class uses a category_set object for creating the symbol set.
