chess4j 1.2 is in the wild. There hasn’t been any new development lately in terms of new features or playing strength, but I have put some effort into improving code quality using the excellent Sonar Source tools. Minimal cyclomatic complexity. No circular package dependencies. No critical or major violations. Over 80% test coverage and over 99% rules compliance (the only minor violations being some bogus magic number stuff).
Next on the road map is to wrap up just a bit more testing, playing around with some new Java 7 features to create a parallel performance test, and finally to incorporate some Scala. Fun times ahead!
