ScalaTion is a system and Domain-Specific Language (DSL) for Modeling & Simulation, coded in Scala, which supports multi-paradigm simulation modeling, including dynamics, activity, event, process and state oriented models. Scala is a modern object-oriented, functional programming language that is well-suited for developing simulation engines.

ScalaTion is maintained and developed by Dr. John A. Miller and his team. A list of contributors is provided in the project's wiki.

For more information, please see the README file or the scaladoc generated API Documentation.

New Unicode Operators and Statistical Functions

ScalaTion will include many operators defined using Unicode characters. Currently, these are included in the main devel branch in the repository.

• See: Examples of Unicode Operators
• See: Examples of Statistical Functions (includes one-way Analysis of Variance (ANOVA) in 5 lines of code!)

Those who are interested in playing with these operators and statistical functions now can download the source code for the devel branch by using the following subversion command:

svn checkout http://scalation.googlecode.com/svn/branches/devel/ scalation-devel

Over the next couple of weeks, we will begin merging these changes into the main devel branch. After that, we will work on fixing any remaining bugs and merge these changes into the trunk and offer a new release!
