表达式-(A OR B OR C OR D) AND (!B AND !D)
我知道,对于分布式属性,它持有(a OR b) AND (c OR d) = (a AND c) OR (a AND d) OR (b AND c) or (b AND d)
,但我不确定如果第二组具有AND
,它将如何工作
答案中的步骤会有所帮助。
可能是这样的吗?
(A OR B OR C OR D) AND (!B AND !D)
= (A OR B OR C OR D) AND !(B OR D)
= ((A OR C) OR (B OR D)) AND !(B OR D)
= ((A OR C) AND !(B OR D)) OR ((B OR D) AND !(B OR D))
= (A OR C) AND !(B OR D) OR false
= (A OR C) AND !(B OR D)
这似乎是最小的,因为每个变量出现一次,并且没有明显的矛盾或重复。
