摘要
利用赋值集的随机化方法,在n值乘积逻辑中提出了公式的随机真度,证明了所有公式的随机真度之集在[0,1]中没有孤立点;给出了两公式间的Dπn-相似度与伪距离的概念,并建立了Dπn-逻辑度量空间,证明了此空间没有孤立点。
Dπn-stochastic truth degree of formulas in n-valued product logic is presented by using stochastic method on evaluation sets.It is proved that the set of stochastic truth degree of all formulas has no isolated point in [0,1].The conceptions of Dπn-similarity degree and pseudo-metric on two formulas are given.Dπn-logic metric space is built.And it is proved that this space has no isolated point.
