读论文的时候经常会看到NP-Hard这个词,只知道这么说那么这个问题就是传统数学方法很难解或者不可解的问题,至于准确说出什么是NP-Hard,一直不清楚。查了一下资料,现记录如下。 P问题指的是多项式时间内可解的问题,也称为多项式问题;所有绝对不可能在多项式时间内求解的可解问题,称为指数型问题;还有一类问题属于不可...
NP-complete(NP-complete)与NPhard问题. cook将polynomial-time reduction多项式时间减少(a.k.a, Cook reduction)和np完全性的概念形式化,并证明了一个np完全问题的存在,证明了Boolean satisfiability problem布尔可满足性问题(通常称为SAT),就是是np完全问题。
NP-Hard问题这一术语在阅读论文时经常遇到，很多人对其理解仅停留在“传统数学方法难以解决或不可解”的层面。为清晰阐释NP-Hard的内涵，本文进行归纳。P问题指的是能够以多项式时间解决的问题，属于多项式问题范畴。相对的，那些绝对不可能在多项式时间内求解的可解问题被归为指数型问题。而不可解问题则属...

In contrast, there is a simple polynomial-time algorithm for 1 ×1 rectangles packed in a rectangle. Thus our results are in some sense tight. Hardness Framework. To prove that sliding blocks and other problems are PSPACE-hard, this paper builds a general framework for proving PSPACE-hardness...
