A New Approach to Evaluate GP Schema in Context

Hammad Majeed

Evaluating GP schema in context is considered to be a complex,
and, at times impossible, task. The tightly linked
nodes of a GP tree is the main reason behind its complexity.
This paper presents a new approach to evaluate GP schema
in context. It is simple in its implementation with a potential
to address well-known GP problems, such as identication
of signicant schema, dead code (introns) and module
acquisition to name a few.
It is based on the principle that the contribution of a
schema can be evaluated by neutralizing the eect of the
schema in the tree containing it (container-tree) and then
checking its eect on the container-tree's tness. Its usefulness
is empirically demonstrated along with its limitation.
