Unfit  3.1.1
Data fitting and optimization software
Welcome to Unfit 3.1.1: Data fitting and optimization software

Does Matlab's fminsearch solve your problems but run too slow? Does Scilab handle your problems but runs even slower? Unfit may be the solution you are looking for. Unfit provides access to six popular optimization algorithms through a common and highly customizable interface. The algorithms are:

Want to try, for example, a Hybrid Genetic Algorithm approach? No problem. Just pass the solution from your Genetic Algorithm to one of the local minimizers and you are done. All it takes is two extra lines of code.

To solve your own optimization problems, all you need to do is to write your own cost function. It can be very simple (see our Parabolic example) or it can be as complex as you like.

We have designed Unfit with the following key features:

Check out our web page for a tutorial on how to write your own cost function, and (if interested) our guide on how to write your own optimizer using the Unfit framework.
