3 Regression Related Studies

Many studies have used the Regression problem domain as a testbed. The problem has been characterised by both Daida et al. (2001) and O'Reilly (1998) as being unique in that it contains many conflicts of context and content in the representation. Keijzer (2003) found improvements using interval arithmetic and a simple fitting method, and other improvements were found using more advanced models for symbolic regression of polynomials [Nikolaev and Iba, 2001].
