Rules with brackets in jfuzzylite

[Unknown]

Hi Juan,

I love to work with QTFuzzyLite and jfuzzylite but sadly I cannot find a solution for the following problem.

A rule like this:

if Input1 is first and (Input2 is second or Input2 is third) then Output is out1

works in QTFuzzyLite but with jfuzzylite I get the following error:

ruleBlock.addRule(Rule.parse("if Input1 is first and (Input2 is second or Input2 is third) then Output is out1", engine));

Exception in thread "main" java.lang.RuntimeException: [syntax error] logical operator <or> expects two operands, but found <3>
	at com.fuzzylite.rule.Antecedent.load(Antecedent.java:246)
	at com.fuzzylite.rule.Rule.load(Rule.java:203)
	at com.fuzzylite.rule.Rule.parse(Rule.java:219

I would be grateful for any hints.

Thank you very much
Mirco

Hi,

thank you for your post.

There was a bug in jfuzzylite 5.0 which caused this issue. This has been resolved in jfuzzylite 5.0.1. Please download from

http://fuzzylite.com/download/jfuzzylite5/
or
https://github.com/fuzzylite/jfuzzylite/releases/download/5.0.1/jfuzzylite-5.0.1.jar

Where did you originally downloaded the library from? Are you using Maven? If so, updating the version to 5.0.1 should work too. Please, let me know.

Cheers.

Hi Juan,

thank you very much. Yes I use Maven, but jfuzzylite is only available in as version 5.0. But it works. 🙂

Thank you very much.
