The current version includes distributions of string edit, interval
arithmetic and simple components packages. It provides implementations of:

- Confidence factors with the operations not, and, or, xor, +, *;
- Classical fuzzy sets with the set-theoretic operations and the operations
of the possibility theory;
- Intuitionistic fuzzy sets with the operations on them;
- Fuzzy logic based on the intuitionistic fuzzy sets and the possibility
theory;
- Fuzzy numbers both integer and floating-point ones with conventional
arithmetical operations;
- Dimensioned fuzzy numbers;
- Fuzzy linguistic variables and sets of linguistic variables with
operations on them;
- Dimensioned fuzzy linguistic variables and sets;
- String-oriented I/O is supported;

The software is distributed under GM GPL.

New in this release:

A rich GUI interface based on GTK+ (The GIMP Toolkit portable across many
operating systems including Windows and Linux). The provided set of widgets
and tree view cell renderes covers:

- Indication and editing of truth values;
- Editing and viewing of fuzzy sets, intuitionistic fuzzy sets and
classification in textual and as a list;
- Editing and viewing sets of linguistic variables.

The linguistic variables sets editor features:

- Domain set view representing individual membership functions of the
variables;
- Annotated axes of the domain view;
- Dimensioned domains support;
- Scroll bars of the domain view axes;
- Multiple selection of the variables and individual points of membership
functions;
- Visual selection of the variables and points of their membership
functions in the domain;
- Indication of the selected variables;
- Indication of the selected points of the membership functions of;
- Searching for the points of the membership functions;
- Indication of an accumulated set of the linguistic variables;
- Editing of the accumulated sets;
- Zooming the widget along its axis;
- Zooming in and out per selection of a rectangular area;
- Scrolling the widget;
- Undo/redo buffer for editing;
- A separate undo/redo buffer for all actions changing the visual
appearance of the widget;
- Tracking the mouse cursor in the widget;
- Indication and editing the names of the variables in the set in a tree
view;
- Indication and editing the points of the membership functions of
individual variables in the tree view;
- Checking names for legality and duplication, indication of illegal names;
- Moving groups of selected points of the membership functions along the
axis per mouse;
- Adding, removing, moving variables in the set;
- Adding, removing points of the variables;
- Applying operations, such as not, and, or, xor to the selected variables
and inserting the result of.
