Robocode - generate robots automagically with JGAP

Let Genetic Algorithms (more specific: Genetic Programmic) do the work for you.
Here you will find more information about that and how to obtain the source code (of course you can try for yourself).

Another article covers some general overview of RobocodeJGAP (written in German).

Have fun creating robots in Java with RobocodeJGAP and Genetic Algorithms!

JGAP 3.3.3 released (Java Genetic Algorithms Package)

JGAP is a sophisticated Genetic Algorithms and Genetic Programming package written in Java.

JGAP version 3.3.3 is an extensive release, featuring basically the following:

• The evolution cycle has been revamped and simplified for a better understanding
• A lot of smaller enhancements and architectural improvements, see the change log
• Some bugs have been fixed
• The basic MinimizingMakeChange example was simplified
• Improved grid computing by adding new classes and features
• Javadoc-enhancements
• New JUnit tests

JGAP 3.3.1 released - Java Genetic Algorithms and Genetic Programming Package

JGAP is a sophisticated Genetic Algorithms and Genetic Programming package written in Java.

JGAP version 3.3.1 is a feature enrichment release.

For the first time, the XStream library is used for serialization issues, making such much more convenient.
Besides, the fast and stable trove4j map implementation is utilized. With that, unit tests relying on maps now don't fail any longer due to specific Java 6 map implementations.
Genetic Programming capabilities have been enhanced a lot, including better cloning support for GA and GP entities.
Robocode 1.5 has been integrated with JGAP in the RobocodeJGAP sibling project.
Besides, some bugs have been fixed, some unit tests were added, Javadoc has been improved and naming conventions of test classes have been enforced for a better Maven support.

This release can be downloaded here.

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.

LINQ is great but is 20 years too late

LINQ is the Language-Integrated Query. Microsoft has the LINQ project running for integrating database queries into C#. Sort of looks like this (example taken from DevelopMentor):

IEnumerable < Product > prodQuery =
            from p in db.Products
            where p.Category.CategoryName == "Beverages" 
            select p;

Sort of this is what I'm missing for long in Java!!!
Before getting to euphoric about the idea behind LINQ, one should consider a solid and very mature system as SAP (to be exact: the SAP base module, BC).
SAP' native language ABAP supports direct query code to be part of an original ABAP code. I think this is possible since about 20 years.

Congrats to Microsoft and others for not recognizing the need for language-integrated database queries earlier. At leats LINQ adds an additional benefit for querying collections in an SQL-like manner.

JGAP 3.2.2 released: Java Genetic Algorithms and Genetic Programming Package
