美国教授 bill Hofmann并非第一次为我刊写文章。在去年第 11期,我们就曾读过他的“答一位65岁的中国老人问”。我们曾约请几位美国教授撰文。谈西方的一个重大节日:Christmas,在几篇来稿中,bill教授的文章让我们编辑先睹为快,齐声叫好！他的文章,不是浮光掠影地描述些我们已经略知一二的圣诞节热闹场面,而是抒发了自己对这个节日的观察和分析,我们不想用“振聋发聩”这样的字眼去形容他的文章,但是,此文确实如一杯浓郁的咖啡,值得细细品味其袅袅的金香。文章不仅有人本的观察,到位的分析,而且,其文字也非常优美。我们非常感谢bill教授为本刊撰稿。应本刊的要求,bill教授对自己的个人情况,作了简单的自我介绍。全文如下: I recently retired after 35 years of teaching writing at the university andcollege *** to that,I worked as a technical writer at the BoeingCompany,and recently as a researcher and exhibits writer at the Museum ofFlight,hoth in Seattle,*** a consultant,I worked for 8 years as aneditor and writer for the Warren Reading *** a freelance writer,Ihave authored books and shorter works in both fiction and non-fiction.I

It’s one o’clock on a clear night, one of those rare occasions in Beijing when the weather is neither too hot nor too cold. I decide to get some exercise and walk home after a nice relaxing dinner with friends. As I’m strolling past the south gate of Ritan Park, I notice the lights are still on at a place I haven’t seen before. ’Zing’ it reads. I try the door, thinking that one more for the road won’t hurt. Cautiously making my way past a row of tables flanking a row of gargoyles to my right, I am greeted by a charming

This is really three articles. It is about hunger, about politics, and about theunreliability of much information in the U. S. media. No one can deny that there are some hungry people in the U. S.. Despite thefact that our employment rate is the highest on record, there are some people whoare chronically unemployed or unemployable because they lack the skills ormotivation, or because their health-either physical or

作者： bill Symington

The two-lane highway from Nanjing to Shanghai, completed only a few years ago, has already turned into a bottleneck. It seems that the people in charge of planning the road system, in whatever country, have a tendency to underestimate people’s fondness for motor vehicles. Unlike the situation in places like the United Kingdom or Germany, however, where widening a road can take several decades, no time is being wasted by the powers that be in Jiangsu Province. It’s a costly exercise, for sure, but this is the richest part of

Do Almost All Trees Have No Perfect Dominating Set?

A graph G is said to have a perfect dominating set S if S is a set of vertices of G and for each vertex v of G, either v is in S and v is adjacent to no other vertex in S, or v is not in S but is adjacent to precisely one vertex of S. A graph G may have none, one or more than one perfect dominating sets. The problem of determining if a graph has a perfect dominating set is NP-complete. The problem of calculating the probability of an arbitrary graph having a perfect dominating set seems also difficult. In 1994 Yue [1] conjectured that almost all graphs do not have a perfect dominating set. In this paper, by introducing multiple interrelated generating functions and using combinatorial computation techniques we calculated the number of perfect dominating sets among all trees (rooted and unrooted) of order n for each n up to 500. Then we calculated the average number of perfect dominating sets per tree (rooted and unrooted) of order n for each n up to 500. Our computational results show that this average number is approaching zero as n goes to infinity thus suggesting that Yue’s conjecture is true for trees (rooted and unrooted).
