Demonstration

• Plots of realized fuzzy sets
• Plots of available fuzzy complements
• Plots of available fuzzy norms
• Some examples of operations on sets

Examples

Some examples can be found at examples. They are not completely documented, but have a source documentation, so one can at least see what's happen there.

There are also some examples which use the Fuzzy Control Language to define their fuzzy systems.

• An inverted pendulum control (needs also the common part)
• A container crane control (uses FCL) (needs also the common part)
• And some others ...

News / Changes

Here some news/changes/highlights in the current version in SVN.

• Reads Fuzzy Control Language files, if the antrl python runtime is available.
• Fuzzification and defuzzification methods are now own objects to be assigned to variables.

Latest Release

The current release is 0.1.0. There changed several things against the previous release (0.0.2 from 2003), so old stuff probably won't work without adaption.

The most current version can be found in the SVN repository.

• Go to the source code

• Download the releases from the project's download page.

Installation

• Extract the downloaded archive. (If you got it directly from SVN you don't need to do this step.)
• Execute python setup.py install to install the package (or python setup.py help for more information about valid options.)

• For reading of FCL files, you need to install the ANTLR3 Python runtime before installation of pyfuzzy.
• For the included demos you need gnuplot and Gnuplot.py.
• Also you might install the dot tool of the graphviz package.
