RobocodeJGAP 0.2.5 released

Robocode is a game. There is a playfield in which two virtual robots fight against each other. A robot can perform certain actions, like moving around, scanning the environment, shooting and turning the gun. Robocode notified a robot if a significant event occurs, including: scanned the opponent, hit a wall, hit by a bullet or hit the opponent.

RobocodeJGAP enables JGAP to generate code for robots playing at Robocode. JGAP produces pure Java code by means of the so-called Genetic Programming. This new version enhances the evolution process and thus enables to find better robots. The newest Robocode version 1.4.9 is supported and integrated.
