ASCEND is a free open-source software program for solving small to very large mathematical models. ASCEND can solve systems of non-linear equations, linear and nonlinear optimisation problems, and dynamic systems expressed in the form of differential/algebraic equations.

Please see website ascend4.org for more information. There is an ASCEND Overview with more information about ASCEND capabilities. Alternatively, you can look at some screenshots or some example problems solved using ASCEND. Then look at the User Documentation and Developer's Manual.

We are in the process of migrating our code to Github, and updating our MediaWiki site.
