Problem with rules with multiple brackets in latest jfuzzylite

[Unknown]

Hi Juan,

after you helped me a lot few month ago sadly a similar problem occurred.

Exception in thread "Application Thread" java.class2.RuntimeException: [rule error] the following rule is not loaded: if Item1 is class1 and Item2 is class2 and ((Item3 is class3 and Item6 is class3 and Item4 is class3 and Item5 is class1) or 
(Item3 is class3 and Item6 is class3 and Item4 is class1 and Item5 is class3) or (Item3 is class3 and Item6 is class1 and Item4 is class3 and Item5 is class3) or 
(Item3 is class1 and Item6 is class3 and Item4 is class3 and Item5 is class3)) then Result is res1
    at com.fuzzylite.rule.Rule.activationDegree(Rule.java:110)

May you have a look at it?

Thank you very very much

hi,

thanks for your post.

Please, export your engine to FLL and use QtFuzzyLite to detect where the problem is. It is likely you have misspelled a variable somewhere.

Cheers.

Hey Juan,

thank you very much. It actually happens with a FLL file exported from QtFuzzyLite.

Hi Mirco,

thank you very much for your post.

The problem you encountered is a bug in jfuzzylite-5.0.1, where double parentheses are not properly parsed. This has been fixed in the master branch https://github.com/fuzzylite/jfuzzylite and a new release has been submitted.

Please, download the latest stable from: https://github.com/fuzzylite/jfuzzylite/releases/tag/5.0.2

Thanks again for taking the time posting about this issue.

Cheers.
