A C++ FuzzyEngine library is implemented.
Update CMake to the latest version (pip command must be available):
sudo apt remove cmake
sudo pip install cmake --upgrade
Go to the Fuzzy directory:
cd build
cmake ..
make
This project contains some unit tests for Fuzzy and DySySim. Install the C++ UnitTest++ library.
DySySim uses C++ Boost Spirit X3.
Install logging lib spdlog.
For creating diagrams gnuplot is used.
Tipping problem fuzzy rules, using the FuzzyEngine library code:
IF service is poor OR food is rancid THEN tip is cheap
IF service is good THEN tip is average
IF service is excellent OR food is delicious THEN tip is generous with 0.5
IF service is excellent AND food is delicious THEN tip is generous with 1.0
- TippingFIS v0.4.1 --------------------------------------------------
Service = poor (0, 0, 2.5, 5) input = 0 mbs = 0
Service = good (2.5, 5, 7.5) input = 0 mbs = 0
Service = great (5, 7.5, 10, 10) input = 0 mbs = 0
Food = rancid (0, 0, 1.5, 4) input = 0 mbs = 0
Food = delicious (6, 8.5, 10, 10) input = 0 mbs = 0
Tip = cheap (0, 5, 10) mbs = 0
Tip = average (10, 15, 20) mbs = 0
Tip = generous (20, 25, 30) mbs = 0
not a = 1 - a
a and b = min(a, b)
a or b = max(a, b)
not a = 1 - a
a and b = max(a+b-1, 0)
a or b = min(a+b, 1)

DySySim is a very basic TUTSIM look-a-like. TUTSIM was developed in the early 70's for script based simulation of time continuous systems represented in simulation blocks. Only a subset of the TUTSIM simulation blocks are implemented, sometimes with slightly other names.
DySySim uses the .dss extension for the simulation text scripts.
Fuzzy logic and control functions are not (yet) implemented in DySySim simulation blocks. Some hardcoded examples are available.
Go to the scriptsDySySim/RCnetwork directory.
The following DySySim script file RCnetwork.dss is used.
Use the next command:
./simplot.shAll simulation values are calculated. The response diagram is plotted by gnuplot in a .png file.
Further development, testing and debugging are in progress.
