中文摘要
翻译
众所周知,许多图问题都是NP难的,这意味着即使用速度很快的计算机,也不可能在合理的时间内解决这些问题。然而,如果事先知道需要处理的图的类型,有时就有可能为这样的问题构造一个有效的算法。在我的研究中,我考虑在应用程序中出现的或提供对问题的解决方案的洞察的图类,并利用它们的性质来设计多项式时间算法,或者证明这样的算法不太可能存在。目标是了解问题和图属性之间的相互作用,并确定图类和导致高效算法的问题之间的关系。
英文摘要
Many graph problems are known to be NP-hard, which means that they likely cannot be solved in a reasonable amount of time even by a fast computer. However, it is sometimes possible to construct an efficient algorithm for such a problem if something is known in advance about the kinds of graphs that need to be handled. In my research, I consider graph classes that arise in applications or that give insight into a problem's solution, and make use of their properties to design polynomial time algorithms, or to prove that such an algorithm is unlikely to exist. The goal is to understand the interplay between problems and graph properties, and to identify relationships between graph classes and problems that lead to efficient algorithms.
