Hi, thanks for the quick reply.

When using “engine->toString()” it does print out my two inputs, output, and all its proportions as well as my Rule Block. But no matter what I do, I can’t seem to get my output based on mt data input or defuzzify it.

Any help is appreciated.

Here is my code if that helps at all

int main(int argc, char* argv[]) {
    using namespace fl;

    Engine* engine = new Engine;
    engine->setName("CAR_AI");
    engine->setDescription("");

    InputVariable* DistanceVariableInput = new InputVariable;
    DistanceVariableInput->setName("DistanceVariableInput");
    DistanceVariableInput->setDescription("");
    DistanceVariableInput->setEnabled(true);
    DistanceVariableInput->setRange(-1.000, 1.000);
    DistanceVariableInput->setLockValueInRange(false);
    DistanceVariableInput->addTerm(new Trapezoid("FarLeftOfLine", -1.000, -1.000, -0.900, -0.600));
    DistanceVariableInput->addTerm(new Trapezoid("LeftOfLine", -0.900, -0.600, -0.400, -0.100));
    DistanceVariableInput->addTerm(new Triangle("OnLine", -0.100, 0.000, 0.100));
    DistanceVariableInput->addTerm(new Trapezoid("RightOfLine", 0.100, 0.400, 0.600, 0.900));
    DistanceVariableInput->addTerm(new Trapezoid("FarRightOfLine", 0.700, 0.900, 1.000, 1.000));
    engine->addInputVariable(DistanceVariableInput);

    InputVariable* LinearVelocityInput = new InputVariable;
    LinearVelocityInput->setName("LinearVelocityInput");
    LinearVelocityInput->setDescription("");
    LinearVelocityInput->setEnabled(true);
    LinearVelocityInput->setRange(-1.000, 1.000);
    LinearVelocityInput->setLockValueInRange(false);
    LinearVelocityInput->addTerm(new Trapezoid("MovingLeftFast", -1.000, -1.000, -0.800, -0.600));
    LinearVelocityInput->addTerm(new Trapezoid("MoveingLeft", -0.800, -0.600, -0.300, -0.100));
    LinearVelocityInput->addTerm(new Triangle("GoingStraight", -0.800, 0.000, 0.800));
    LinearVelocityInput->addTerm(new Trapezoid("MovingRight", 0.100, 0.300, 0.600, 0.800));
    LinearVelocityInput->addTerm(new Trapezoid("MovingRightFast", 0.600, 0.800, 1.000, 1.000));
    engine->addInputVariable(LinearVelocityInput);

    OutputVariable* Steering = new OutputVariable;
    Steering->setName("Steering");
    Steering->setDescription("");
    Steering->setEnabled(true);
    Steering->setRange(-1.000, 1.000);
    Steering->setLockValueInRange(false);
    Steering->setAggregation(new Maximum);
    Steering->setDefuzzifier(new Centroid(100));
    Steering->setDefaultValue(fl::nan);
    Steering->setLockPreviousValue(false);
    Steering->addTerm(new Triangle("MakeAHardLeft", -1.000, -1.000, -0.900));
    Steering->addTerm(new Triangle("MakeALeft", -1.400, -0.900, -0.400));
    Steering->addTerm(new Triangle("GoStraight", -1.500, 0.000, 1.500));
    Steering->addTerm(new Triangle("MakeARight", 0.400, 0.900, 1.400));
    Steering->addTerm(new Triangle("MakeAHardRight", 0.900, 1.000, 1.000));
    engine->addOutputVariable(Steering);

    RuleBlock* OutputRule = new RuleBlock;
    OutputRule->setName("OutputRule");
    OutputRule->setDescription("");
    OutputRule->setEnabled(true);
    OutputRule->setConjunction(fl::null);
    OutputRule->setDisjunction(fl::null);
    OutputRule->setImplication(new AlgebraicProduct);
    OutputRule->setActivation(new General);

    OutputRule->addRule(Rule::parse("if DistanceVariableInput is OnLine and LinearVelocityInput is GoingStraight then Steering is GoStraight", engine));
    OutputRule->addRule(Rule::parse("if DistanceVariableInput is OnLine and LinearVelocityInput is MoveingLeft then Steering is GoStraight", engine));
    OutputRule->addRule(Rule::parse("if DistanceVariableInput is OnLine and LinearVelocityInput is MovingLeftFast then Steering is MakeARight", engine));
    OutputRule->addRule(Rule::parse("if DistanceVariableInput is OnLine and LinearVelocityInput is MovingRight then Steering is GoStraight", engine));
    OutputRule->addRule(Rule::parse("if DistanceVariableInput is OnLine and LinearVelocityInput is MovingRightFast then Steering is MakeALeft", engine));

I tried to import fuzzy controllers but the import option was not working. That’s why I came up with this question. Can you please help me with that?

[Unknown]

So without buying a license, I cannot implement my own fuzzy code? Can I make editings to the existing code?

[Unknown]

Sir,
I downloaded fuzzylite from the same link and I have a folder named Qtfuzzylite and in that, I have its executable file. I run that and tipper program is executing by default. I want to create my own cpp engine and to run it instead of this program. How can I make that possible? Expecting your reply. Thank You.

[Unknown]

Hi Juan,

thanks to your string text suggestions I found the licence.

Now QtfuzzyLite is working.

Thank you so much.

Cheers.

Filippo

Good morning Juan,

I am so sorry but one more time I had by pc down, therefore I had to re-install the whole operative system.

It is possible to have the Licence codes of the Fuzzy- Lite once again?
I bought the student licence the 5th of december 2017

Thank you so much

Regards

What method do I call if I want to see a rule which was fired from the rule base?
Example if I have four rules from the tipping problem
takagiSugeno.addRule(Rule.parse(“if service is poor or food is rancid then tsTip is cheap”, engine));
takagiSugeno.addRule(Rule.parse(“if service is good then tsTip is average”, engine));
takagiSugeno.addRule(Rule.parse(“if service is excellent or food is delicious then tsTip is generous with 0.5”, engine));
takagiSugeno.addRule(Rule.parse(“if service is excellent and food is delicious then tsTip is generous with 1.0”, engine));
engine.addRuleBlock(takagiSugeno);

I wan to know which rule is fired in every iteration.
like Cheap, average or delicious

Hi,
see hereunder for compiler revision.
No problem, I have added pragma to ignore this warning.

It worked! Thank you Juan.

Hi Juan,

Here is the generated R code by jfuzzylite.

When you run this code the following error occurs:

Error in textConnection(engine.fld) : object 'engine.fld' not found

So I changed from “engine.fld” to “engine.fldFile” on line 1075. But the original error still persists:

Error: Discrete value supplied to continuous scale
In addition: Warning message:
  Error: Discrete value supplied to continuous scale
