Hi Juan,

I bought and use your “Qtfuzzylite” to design my research it helps me a lot, if you have some knowledge about how it works with Genetic Algorithm please let me know the steps how to use/include genetic algorithm with your jfuzzylite library. and finally can you suggest me the performance evaluation tools and techniques to measure the system designed using your library? Here under i have attached the code fragment which display only the diffuzifed value, but i need you to add the code fragment to display the class or term this output value represents in front of the value.

public static void main(String[] args){
FloodLevelPrediction instance = new FloodLevelPrediction();
Engine engine = instance.getEngine();

for (int j = 0; j < 12; j++) {
double rw = engine.getInputVariable(“RW”).getMinimum() + j * (engine.getInputVariable(“RW”).range() / 5);
for (int i = 0; i < 12; ++i) {
double gr = engine.getInputVariable(“GW”).getMinimum() + i * (engine.getInputVariable(“GW”).range() / 5);

engine.getInputVariable(“RW”).setValue(rw);
engine.getInputVariable(“GW”).setValue(gr);

engine.process();
double output = engine.getOutputVariable(“LT”).getValue();
System.out.println(“RW=” + rw + “, GW” + gr + “->LT=” + output);

}
}
}
}

When I run the program I get the output in number formats (Like ,LT=1.15, where LT is the output variable and 1.15 is the diffuzified value ),but i need also to display the Output Variable terms(in my case the output variable has three fuzzy terms (Normal,Warning and Emergency)) associated with the diffuzified output value. like (LT =1.15 ,Status Normal).
####################
Current System Outputs
RW=4.44, GW4.368->LT=2.15
RW=4.44, GW6.336->LT=5.800730000000002# how to remove this large numbers after decimal point, i need approximate it to two decimal points

My Desire Output
RW=4.44, GW4.368->LT=2.15, Status= Normal
RW=4.44, GW6.336->LT=5.80, Status= Warning

Thanks in advance and I appreciate your cooperativeness.

Hi,

thank you for your post and please excuse me for the late response.

You can use Op.str(engine.getOutputVariable(“LT”).getValue()), where Op.java can be found in com.fuzzylite package

Cheers.
