EpochX is a Genetic Programming (GP) framework written in Java. It allows the creation of tree-based and grammar-based GP systems. It has been created to reflect typical ways in which Java programmers work, for example, borrowing from the Java event model and taking inspiration from the Java collections framework. This paper presents EpochX in general, and(More)
We present a set of extensions to Montana’s popular Strongly Typed Genetic Programming system that introduce constraints on the structure of program trees. It is demonstrated that these constraints can be used to evolve programs with a naturally imperative structure, using common high-level imperative language constructs such as loops. A set of three(More)
EpochX is a genetic programming framework with provision for event management - similar to the Java event model - allowing the notification of particular actions during the lifecycle of the evolutionary algorithm. It also provides a flexible Stats system to gather statistics measures. This paper introduces a graphical interface to the EpochX genetic(More)
Variables are a fundamental component of computer programs. However, rarely has the construction of new variables been left to the evolutionary process of a tree-based Genetic Programming system. We present a series of modifications to an existing GP approach to allow the evolution of high-level imperative programs with limited scope variables. We make use(More)
Loss of radial palmar tilt in malunion of Colles' fractures alters wrist biomechanics, abnormally loading the tenuous dorsal ligament complex. This can result in midcarpal instability with synovitis, pain, weakness, and possible articular degeneration. An osteotomy to correct radius alignment using a trapezoidal corticocancellous bone graft has been(More)
In this study, the retention behaviors of pharmaceutical and drug-like compounds in supercritical fluid chromatography (SFC) with polar stationary phases were evaluated using linear solvation energy relationships (LSERs). We used more than 200 compounds, including mono-, di-substituted benzenes, and other marketed drugs with a wide range of solvation(More)
Ten subjects with unilateral posterior cruciate ligament-deficient knees were studied, comparing the knee mechanics of the affected knee with the mechanics of the opposite normal knee. The static squat test was used to determine knee forces and moments through measurements made on roentgenograms. Statistically significant increases occurred in posterior(More)
