Some simple questions

[Unknown]

Hello Juan Rada-Vilela,

thank you for your library it seams a well structured library. I like the maven compatibility!
Anyway i have some basic (maybe stupid) questions:

For what purpose is it possible to use more than one rule block?

Is it possible to use a Output variable as a input variable? How to do that?

What are the hedges for? How to use them?

I hope you or someone else find some time to answer my questions.

Best Regards,
Waldemar

an additional question:

in package jfuzzylite.jfuzzylite.src.main.java.com.fuzzylite.term i found different types of terms, where do i find the description of the term types?

[Unknown]

i found a small overview of linguistic term types available in the documentation “fuzzylite-paper-3.1.pdf”.

Hi,

thank you for your good questions.

(1) Multiple rule blocks can lead to a better organization over the goals of the engine. You could experiment with multiple input variables and rules at the same time, and also better organize your engine based on the tasks or any other criterion.

(2) You can use an output variable as an input by just using the rule: if outputVariable is ... then anotherOutputVariable is .... Check the following examples in the examples folder: Laundry.fll, SimpleDimmerChained.fll.

(3) Hedges modify the propositions. Please check the bibliography and the examples.

(4) Please find the description of all the terms in the documentation available at:
http://fuzzylite.github.io/fuzzylite/index.html . Furthermore, please check QtFuzzyLite to observe all the terms available.

Cheers.

Thank you for the fast reply and for pointing me to the specific examples!

Thanks for the advice with the QtFuzzyLite, i already had a look at it und it seems a very powerful tool for working with fuzzy logic systems. At the moment i am trying out the library for my private project and as a private person im not able to pay so much only for testing, but maybe after the test phase.

to your answer 1)
Let us assume there are two different rule blocks I and II defined.

for the Laundry Example it would be:

RuleBlock: I
enabled: true
conjunction: Minimum
disjunction: Maximum
activation: Minimum
rule: if Load is small and Dirt is not high then Detergent is less
rule: if Load is small and Dirt is high then Detergent is normal
rule: if Load is normal and Dirt is low then Detergent is less
rule: if Load is normal and Dirt is high then Detergent is more

RuleBlock: II
enabled: true
conjunction: Minimum
disjunction: Maximum
activation: Minimum
rule: if Detergent is normal or Detergent is less then Cycle is short
rule: if Detergent is more then Cycle is long

Does the engine always process the (first defined) rule block I at first?

[Juan Rada-Vilela (admin)]

Yes. In the order they are added.

You can use QtFuzzyLite 4, which is free.

Cheers.
