Number of Conditions in a rule

[Unknown]

Hi!

How many conditions can be put in a rule?

I’ve this code:

ruleBlock.addRule(Rule.parse(“if valor1 is fiv1 and valor2 is fiv2 and valor3 is fiv3 and valor4 is fiv4 and valor5 is fiv5 and valor6 is fiv6 and valor7 is fiv7 and valor8 is fiv8 then salida is fiy”, engine));

..and the console said:
“syntax error] expected variable or logical operator, but found <valor5>”

I don’t know, if the next expression is ok:
engine.configure(“AlgebraicProduct”, “AlgebraicSum”, “AlgebraicProduct”, “AlgebraicSum”, “Centroid”);

I don’t understand it well. I’ve to change it with the same result.

Thanks!.

Hi,

thank you for your post.

There is no limited number on the conditions in the antecedent.

I think that your problem is that you have named a variable different than what you are referring to in the antecedent of a rule. Make sure you have correctly named variable . Else, check it out with QtFuzzyLite.

Cheers.

Yes, it was that.

I continue with many problems in my java’s program. I have to read a file with many datas and to make the inputs, outputs and rules while I read it.

After many problems, I have this engine:

InputVariable: valor1
  enabled: true
  range: -50,000 400,000
  term: fv1_1 Triangle 1,110 1,120 1,130
  term: fv1_2 Triangle 2,110 2,120 2,130
  term: fv1_3 Triangle 3,110 3,120 3,130
InputVariable: valor2
  enabled: true
  range: -50,000 400,000
  term: fv2_1 Triangle 1,210 1,220 1,230
  term: fv2_2 Triangle 2,210 2,220 2,230
  term: fv2_3 Triangle 3,210 3,220 3,230
InputVariable: valor3
  enabled: true
  range: -50,000 400,000
  term: fv3_1 Triangle 1,310 1,320 1,330
  term: fv3_2 Triangle 2,310 2,320 2,330
  term: fv3_3 Triangle 3,310 3,320 3,330
InputVariable: valor4
  enabled: true
  range: -50,000 400,000
  term: fv4_1 Triangle 1,410 1,420 1,430
  term: fv4_2 Triangle 2,410 2,420 2,430
  term: fv4_3 Triangle 3,410 3,420 3,430
InputVariable: valor5
  enabled: true
  range: -50,000 400,000
  term: fv5_1 Triangle 1,510 1,520 1,530
  term: fv5_2 Triangle 2,510 2,520 2,530
  term: fv5_3 Triangle 3,510 3,520 3,530
InputVariable: valor6
  enabled: true
  range: -50,000 400,000
  term: fv6_1 Triangle 1,610 1,620 1,630
  term: fv6_2 Triangle 2,610 2,620 2,630
  term: fv6_3 Triangle 3,610 3,620 3,630
InputVariable: valor7
  enabled: true
  range: -50,000 400,000
  term: fv7_1 Triangle 1,710 1,720 1,730
  term: fv7_2 Triangle 2,710 2,720 2,730
  term: fv7_3 Triangle 3,710 3,720 3,730
InputVariable: valor8
  enabled: true
  range: -50,000 400,000
  term: fv8_1 Triangle 1,810 1,820 1,830
  term: fv8_2 Triangle 2,810 2,820 2,830
  term: fv8_3 Triangle 3,810 3,820 3,830
OutputVariable: salida
  enabled: true
  range: -50,000 400,000
  accumulation: Maximum
  defuzzifier: Centroid 200
  default: nan
  lock-previous: false
  lock-range: false
  term: fy_1 Triangle 1,910 1,920 1,930
  term: fy_2 Triangle 2,910 2,920 2,930
  term: fy_3 Triangle 3,910 3,920 3,930
RuleBlock: 
  enabled: true
  conjunction: AlgebraicProduct
  disjunction: none
  activation: Minimum
  rule: if valor1 is fv1_1 and valor2 is fv2_1 and valor3 is fv3_1 and valor4 is fv4_1 and valor5 is fv5_1 and valor6 is fv6_1 and valor7 is fv7_1 and valor8 is fv8_1 then salida is fy_1
  rule: if valor1 is fv1_2 and valor2 is fv2_2 and valor3 is fv3_2 and valor4 is fv4_2 and valor5 is fv5_2 and valor6 is fv6_2 and valor7 is fv7_2 and valor8 is fv8_2 then salida is fy_2
  rule: if valor1 is fv1_3 and valor2 is fv2_3 and valor3 is fv3_3 and valor4 is fv4_3 and valor5 is fv5_3 and valor6 is fv6_3 and valor7 is fv7_3 and valor8 is fv8_3 then salida is fy_3

Well, when I try these inputs va1 = 1.11; va2 = 1.21; va3 = 1.31; va4 = 1.41; va5 = 1.51; va6 = 1.61; va7 = 1.71; va8 = 1.81;
the output always is the default nan.

I have configured engine with “engine.configure(“AlgebraicProduct”, “”, “Minimum”, “Maximum”, “Centroid”);” and I don’t know if that is correct.

Thanks, and excuse me for my english.

Hi,

thank you for your post.

The best way to find out what is wrong with your engine is using QtFuzzyLite. I strongly suggest you check it out, either version 5 or 4.

Briefly looking at your rules, maybe none of the rules are activating, and hence you obtain NaN.

Cheers.

Thanks!

I’m using QFuzzyLite 4, and I have to delete this var “lock-previous: false” to make work it.

The console give me back this many times:

if valor1 is fv1_1 and valor2 is fv2_1 and valor3 is fv3_1 and valor4 is fv4_1 and valor5 is fv5_1 and valor6 is fv6_1 and valor7 is fv7_1 and valor8 is fv8_1 then salida is ?
#[variable error] term <?> not found in variable <salida> {\src\variable\Variable.cpp::fl::Variable::getTerm() [line:167]}
# Total rules: 6561. Good Rules: 0. Bad Rules: 6561.

I don’t know what means. Gracias!
