从概率论的观点探讨CNF-SAT

摘要:

本文提出了一种新的方法来确定一个逻辑(CNF)公式是否满足或不使用概率论方法。此外,我们将介绍一种算法,在某些情况下,加快标准解决方案(CNF-SAT)。已知任何(CNF)公式都以$2^n$的时间复杂度求解,其中n是(CNF)公式中不同文字的数量。在我们的方法中,我们将从概率的角度遵循一种增强的方法,该方法并不总是随着不同文字的数量呈指数级增加。这将增加确定一个大公式在许多情况下是否可满足的机会。此外,我们将指出一些有前途的性质,遵循应用概率论的概念和公理的逻辑,这可能会产生更多的见解的可满足性的逻辑公式。

英文摘要:

The following paper proposes a new approach to determine whether a logical (CNF) formula is satisfiable or not using probability theory methods. Furthermore, we will introduce an algorithm that speeds up the standard solution for (CNF-SAT) in some cases. It is known that any (CNF) formula is solved with a time complexity of $2^n$ where n is the number of different literals in the (CNF) formula. In our approach, we will follow an enhanced method from a probabilistic point of view that does not always increase exponentially with the number of different literals. This will enhance the chance of determining whether a large formula is satisfiable or not in many cases. Additionally, we will point out at some promising properties that follow from applying probability theory concepts and axioms to logic, which might originate more insights about the satisfiability of logical formulas.
