P vs. NP是理论计算机领域最重要的课题之一,而其中的核心是NP完全问题. 由于该问题所涉及的概念复杂抽象,对它们的理解存在不少谬误,许多已发表的研究论文都包含着这些谬误. 主要是:NP、NP完全概念理解谬误,确定性及非确定性图灵机的概念模糊不清,P与NP关系的误读,NP问题研究方向的误导等. 本文分析了这些谬误,并揭示了相关概念的实质. 通过不同角度多方位分析,对NP完全问题可能的解决途径和研究方向,提供了启发式思路.
P vs. NP是理論計算機領域最重要的課題之一,而其中的覈心是NP完全問題. 由于該問題所涉及的概唸複雜抽象,對它們的理解存在不少謬誤,許多已髮錶的研究論文都包含著這些謬誤. 主要是:NP、NP完全概唸理解謬誤,確定性及非確定性圖靈機的概唸模糊不清,P與NP關繫的誤讀,NP問題研究方嚮的誤導等. 本文分析瞭這些謬誤,併揭示瞭相關概唸的實質. 通過不同角度多方位分析,對NP完全問題可能的解決途徑和研究方嚮,提供瞭啟髮式思路.

P versus NP is one of the most important problems in theoretical computer science. Because the concepts about it are very abstract and complicated, some scholars and students in computer science often misunderstand them. A lot of published papers contain these misunderstandings. The main problems are: the defaults in understanding the concepts of NP and NPC, unclearly understanding the concepts of deterministic turing machine and non-deterministic turing machine, misreading the relationship of P and NP and mislead-ing in the study direction of NP, etc. Of all these concepts, the core concept is the NP-complete problem. In this paper, we analyzed the misunderstandings. By deeply studying the definitions, we revealed their essence. Specially, by analyzing a lot of questions in different fields, we gave some heuristic strain of thoughts for the possible ways to solve the NP-complete problem and the possible directions to study it.
