Orbital library

Overview

The Orbital library is a Java class library providing object-oriented representations and algorithms for logic, mathematics, and artificial intelligence. It comprises theorem proving, computer algebra, search and planning, as well as machine learning algorithms.

Generally speaking, the conceptual idea behind the Orbital library is to provide extensional services and components for Java, which surround the heart of many scientific applications. Hence the name Orbital library. In order to satisfy the requirements of high reusability, the design of this foundation class library favors flexibility, conceptual simplicity and generalisation. So many sophisticated problems can be solved easily with its adaptable components.

News

• 06/14/2009: A recent publication [1] indicates in real world benchmarks that the compared functionality in the Orbital library is competitive in performance to other tools

Statistics

The Orbital library provides you with access to mathematical, algorithmic, and logical functionality. It comprises:

• 38,588 SLOC (Source Lines of Code, i.e., not counting comments), counted using David A. Wheeler's 'SLOCCOUNT'
• 284 public classes and interfaces in 14 packages
• The interfaces provide access to implementations in 5 additional implementation packages totaling 870 classes, including inner classes.
