中文摘要
我研究的主要目的是了解计算机程序在解决某些重要类型问题方面的局限性。这些问题是有一定数量的条件需要满足的问题;假设给定的条件集合,很容易检查所提出的解决方案实际上是否正确,但似乎很难搜索到解决方案。这类问题的一个日常例子是由拼图游戏或解魔方的难题提供的。这些类型的问题属于NP类别。其中,最著名的是来自逻辑的可满足性问题,即命题逻辑公式是否具有满意赋值的问题。
英文摘要
The principal aim of my research is to understand the limitations of computer programs in solving certain important types of problems. These problems are ones where there are a certain number of conditions to be satisfied; assuming a given collection of conditions, it is easy to check whether or not a proposed solution is in fact correct, but it appears to be difficult to search for a solution. An everyday example of this kind of problem is provided by puzzles, such as jigsaw puzzles, or the problem of solving Rubik's Cube. These type of problems are in the category NP. Of these, the best known is the Satisfiability problem from logic, which is the problem of whether a formula of propositional logic has a satisfying assignment.
