Announcing the release of a free (for research use) constraint solver: Cassowary Constraint Solver for Smalltalk, C++, and Java Version 0.60 Web Page: http://www.cs.washington.edu/research/constraints/cassowary Distribution: ftp://ftp.cs.washington.edu:/pub/constraints/code/cassowary/ Contact: cassowary@cs.washington.edu Greg J. Badros and Alan Borning University of Washington Computer Science and Engineering 15-December-1999 with Constraint Drawing Applet (CDA) by Michael Noth Cassowary is an incremental constraint solving toolkit that efficiently solves systems of linear equalities and inequalities. Constraints may be either requirements or preferences. Client code specifies the constraints to be maintained, and the solver updates the constrained variables to have values that satisfy the constraints. A technical report is included in the distribution that describes the algorithm, interface, and implementation of the Cassowary solver. Additionally, the distribution contains toy sample applications written in Smalltalk, C++, Java, and Python, and a more complex example Java applet, the "Constraint Drawing Application". More information is available on our web page: http://www.cs.washington.edu/research/constraints/cassowary See README for more details on getting started using these packages. See NEWS for a history of user-visible changes. See LICENSE for legalese regarding use of this distribution.
