This paper provides an empirical test of a hypothesis, which describes the effects of structural mechanisms in genetic programming. In doing so, the paper offers a test problem anticipated by thisâ€¦ (More)

This paper presents methods to visualize the structure of trees that occur in genetic programming. These methods allow for the inspection of structure of entire trees even though several thousands ofâ€¦ (More)

This paper presents a hypothesis about an undiscovered class of mechanisms that exist in standard GP. Rather than being intentionally designed, these mechanisms would be an unintended consequence ofâ€¦ (More)

This work introduces visualization techniques that allow for a multivariate approach in understanding the dynamics that underlie genetic programming (GP). Emphasis is given toward understanding theâ€¦ (More)

The Maximum Likelihood (ML) problem in phylogenetics is an optimization problem where we seek to find the model tree of maximum probability given a specific evolutionary model. Solving the problemâ€¦ (More)
