Jess 和 FuzzyJ 的协助

我正在尝试学习 Jess 和 FuzzyJ,但在运行一个简单的程序时遇到问题。我已经看了几个小时了,但不太确定为什么它不运行。如果有人能指出我正确的方向,我将不胜感激。

(defglobal ?*liquidity* =
    (new nrc.fuzzy.FuzzyVariable "liquidity" 0.0 1.0 "index"))

    (printout t "Enter the stability index(ex. 0.64): ")
    (bind ?stability-value (float(readline t)))


    (assert(theIncome
        (new nrc.fuzzy.FuzzyValue ?*income*
        (new nrc.fuzzy.TriangleFuzzySet
        (- ?income-value 3000.0)
        ?income-value

I'm trying to learn Jess and FuzzyJ but am having problems getting a simple program to run. I have looked at it for hours and am no quite sure why it doesn't run. If someone could point me in the right direction it would be very much appreciated.

这个程序有很多小的语法错误;总的来说,杰西的翻译在指出这些问题方面做得很好。首先,在每个评论块中,您都有评论的实际文本......未评论。因此,例如,在“模糊变量”等行的开头添加一个分号。

其次,该行

(?*liquidity* addTerm "high" (new SFuzzySet .7 . 9))

最后一个小数点后不应有空格。

第三,规则 rule-1rule-2 末尾没有足够的右括号。任何能够格式化 Lisp 代码的体面程序员编辑器都应该能够帮助您解决这个问题。

第四,在该行中,

(theStability ?y (fuzzy-match ?y "high"))

谓词函数之前缺少“&:”——请参阅上一行。

最后,我认为该行格式

retract( ?f)

错误 - 应该是 (retract ?f)

There are many small syntax errors in this program; in general the Jess interpreter does a good job of pointing them out. First of all, in each of your comment blocks, you've got the actual text of the comment... not commented. So add a semicolon to the beginning of the lines like "Fuzzy Variables", for instance.

Second, on the line

(?*liquidity* addTerm "high" (new SFuzzySet .7 . 9))

there ought to be no space after that last decimal point.

Third, the rules rule-1 and rule-2 don't have enough close-parentheses at the end. Any decent programmer's editor able to format Lisp code should be able to help you fix that.

Fourth, on the line

(theStability ?y (fuzzy-match ?y "high"))

you're missing the "&:" before the predicate function -- see the previous line.

Finally, I think, the line

retract( ?f)

is malformed -- should be (retract ?f) .
