我希望在运行规则时增加安全性。现在它什么都没改变。事实(human_resources n)确实存在。
(defglobal? security = 0)
(defrule rule1 (human_resources n) => (defglobal? security =(+? security 1)) )
这导致?* security = 1: (defglobal?安全 = 0) (defglobal? security =(+? security 1))
答案 0 :(得分:6)
CLIPS> (defglobal ?*security* = 0)

(defrule rule1
(human_resources n)
=>
(bind ?*security* (+ ?*security* 1)))
CLIPS> (reset)
CLIPS> ?*security*
0
CLIPS> (assert (human_resources n))
<Fact-1>
CLIPS> (run)
CLIPS> ?*security*
