The P versus NP problem is the determination of whether all NP-problems are actually P-problems. If P and NP are not equivalent, then the solution of NP-problems requires (in the worst case) an exhaustive search, while if they are, then asymptotically fa
Math:P问题(多项式时间内可解决)、NP问题(多项式时间内验证)、NPC问题(可通过一个多项式时间算法转换为NP问题)、NP-Hard问题(两不知)的详解与区别之详细攻略 导读:昨天与圈内几位数学界的大佬,深度探讨了一下P问题、NP问题、NPC问题、NP-Hard问题之间的联系和区别,聊的很嗨,主要是来比较复杂问题的困难程度,...
Mathematics is based on a lot of assumptions. Some of those assumptions last decades before being proved true or false. As long as the assumption that P doesn’t equal NP remains true, then we can keep sharing secrets, email and credit-card numbers on the Internet without any problems. If...
1,判断是否为NP问题,通常较容易; 2,找到一种方法,使其能够在多项式时间内规约为某个已经被证明为是NPC问题的问题 综上,概括P,NP,NPC的关系; 1,P是NP; 2,NPC是NP; 3, NP是否=P,不明 4,NPC和P是否有交集? 不明; 但如果有,则有 P=NP >NPC ( 大于,小于号是包含的意思) 如果没有交集;则P=NP不...

Definition: NP is the class of problems which have a polynomial-time verifier. That is, given an input w to a problem A∈NP, there is a string c called a certificate and a Turing machine M for which M verifies that c proves w∈A and runs in polynomial time. This definition is a ...
vs NP存在难以克服的局限性;目前的共识是,如果P vs NP被解决,那必然是在数学工具上出现了突破性的...
Moreover, the P vs NP problem also has implications for the ontology of mathematics and the nature of reality.If P=NP, it would mean that there is an underlying simplicity to the universe, with problems that seem complex on the surface having efficient, elegant solutions.In contrast, if P...

1. 至2021年,P/NP问题已经50岁了,但其解决方案仍遥不可及。尽管算法与硬件的卓越进步使我们可以解决许多NP完全问题,但在密码系统的破解方面仍进展甚微。2. 随着我们持续地在机器学习以及以数据为中心的计算领域取得激动人心的进步,P/NP问题向我们提供了一个宝贵的视角,去了解在未来的机器学习领域什么是可能的...
