在不修改現有規則的情況下計算已解除規則

Question

如何計算在CLIPS中執行程序期間觸發了多少規則？但我不想修改現有規則，比如在每個規則中添加一個計數器。

Answer 1

使用（表統計）命令：

CLIPS> (clear) 
CLIPS> (defrule rule-1 (data ?) =>) 
CLIPS> (assert (data 1) (data 2) (data 3)) 
<Fact-3> 
CLIPS> (watch statistics) 
CLIPS> (run) 
3 rules fired  Run time is 1.60000054165721e-05 seconds. 
187499.936524567 rules per second. 
4 mean number of facts (4 maximum). 
1 mean number of instances (1 maximum). 
2 mean number of activations (3 maximum).
