Question

在剪辑中，我在内存中有以下事实。我想通过某种规则重新生成它。当我重新生成它时，它不会将其添加到事实中。因为所有字段值都相同。解决这个问题的方法是什么？

(objct (name food) (edible? yes) (isa Object))

Answer 1

基本编程指南，第13.4.4节，设置事实的重复行为。 http://clipsrules.sourceforge.net/documentation/v630/bpg.pdf

CLIPS> (clear)
CLIPS> (deftemplate objct (slot name) (slot edible?) (slot isa))
CLIPS> (assert (objct (name food) (edible? yes) (isa Object)))
<Fact-1>
CLIPS> (assert (objct (name food) (edible? yes) (isa Object)))
FALSE
CLIPS> (facts)
f-0     (initial-fact)
f-1     (objct (name food) (edible? yes) (isa Object))
For a total of 2 facts.
CLIPS> (set-fact-duplication TRUE)
FALSE
CLIPS> (assert (objct (name food) (edible? yes) (isa Object)))
<Fact-2>
CLIPS> (facts)
f-0     (initial-fact)
f-1     (objct (name food) (edible? yes) (isa Object))
f-2     (objct (name food) (edible? yes) (isa Object))
For a total of 3 facts.
