Amiba is a Gene Expression Programming (GEP) framework for Java. GEP is, like genetic algorithms, a branch of evolutionary computing. The framework separates the process of evolution from the process of interpretation of the chromosome, allowing the use of various schemes. For example, graphs may be used as terminals and graph operations as operators in the chromosome instead of the usual double precision numbers. It implements mutation, transposition, and recombination. Options and rates are easily configured through an XML file. A mechanism to load fitness cases in bulk is also provided.
Simple simeng (simple simulation engine) is a bare bones Java-based discrete simulation engine that uses variable time steps. Events are inserted in an ordered queue, and time is advanced based on the time the next event needs to be executed instead of discrete predefined timesteps. Entities can send events directly to other entities (one-2-one), or events can be broadcast to subscribed entities (one-2-many). The simplicity of the engine makes it suitable for educational purposes.
Sambuca is a Java HTTP server framework that allows developers to embed an HTTP server directly in their applications with custom HTTP request handlers, so that their application can directly process incoming HTTP requests and easily send back HTTP formatted responses to the requesting client. Applications can host standalone HTTP services such as Web Services without having to deploy and integrate with a full application server such as Tomcat, JBoss, or WebLogic.
SWTBot is a Java-based functional testing tool for testing SWT and Eclipse based applications. It provides APIs that are simple to read and write and hide the complexities involved with SWT and Eclipse. This makes it suitable for functional testing by everyone. A set of assertions that are useful for SWT are provided, and you can also use your own assertion framework. A recorder and driver are provided for recording and playing back tests along with Ant tasks so that you can run your builds from within CruiseControl or other CI tools.
