报告题目：Trees with minimal atom-bond connectivity index - recent theoretical and computational results
报告人：Darko Dimitrov (研究员, Hochschule fuer Technik und Wirtschaft Berlin)
报告简介：The problem of characterizing trees with minimal atom-bond connectivity index is one of the most demanding open problems in chemical graph theory. The problem is not yet completely solved, but there was significant progress in the last several years heading towards its final solution. We will give an overview of the recent theoretical results as well as an overview of some computational approaches, which help us to better understand the structure of the trees with minimal atom-bond connectivity index.
