OverviewThe Orbital library is a Java class library providing object-oriented representations and algorithms for logic, mathematics, and computer science. This Java library provides computer algebra, numerical algorithms, theorem proving, search and planning etc. 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. Orbital library is designed with the goals of flexibility, conceptual simplicity and general applicability. You can get this Java library and its documentation here:
- 06/14/2009: A CADE-22  indicates that the functionality in the Orbital library that has been used in these benchmarks is competitive in performance to other tools. This does not predict what will happen in other circumstances.
The Orbital library provides you with access to mathematical, algorithmic, and logical functionality.
- 38,818 LOC (Lines of Code, i.e., not counting comments)
- 284 Java files with classes and interfaces in 14 packages
- The interfaces provide access to implementations in 5 additional implementation packages totaling 870 classes, including inner classes.
Selected PublicationsThe Orbital library is used in a fair number of projects. It has also been mentioned in the following papers (among other publications) and is used in the underlying implementations:
