engine.process();
//System.out.print(new JavaExporter().toString(engine));
System.out.print(engine.getOutputVariable(“snake”).fuzzyOutput());
return String.format(“”, engine.getOutputVariable(“snake”).fuzzyOutput());
}
}

out put:snake: Aggregated Maximum[Minimum(1.000,Saw_scaled_viper)]
I need get single value inside bracket

Saw_scaled_viper

Hi,

thanks for your post.

Maybe something like this could work:

Aggregated fuzzyOutput = engine.getOutputVariable(“snake”).fuzzyOutput();
for (Activated activated : fuzzyOutput.getTerms()){
   System.out.println(String.format("%f %s", activated.getDegree(), activated.getTerm().getName()));
}

If not, please check the source code of Aggregated and Activated terms under com.fuzzylite.term.

Cheers.
