关于图论中完全匹配的一道题目
一道图论题目:设R是A到B的一个关系且|A|=|B|=n,证明:如果在A,B和R相对应的网络中,每一个节点的度数至少是n/2,那么对于A,B和R,存在一个完全匹配.提示是利用哈密尔顿回路回路存在性的一个定理:如果n个顶点的连通图每个顶点的度数至少为n/2,那么该图必定存在一条哈密尔顿回路.

我将所述之图理解为一个二部图,记为G,部集为A和B,关系R则是边集.由于图中存在一条Hamilton回路,记此回路为H,则H为G的生成子图.在H中,因点集A中的点之间没有边相连,且每个点的度数为2 (对于B也一样),故H是一个2正则的二部图.由于“任意 r 正则二部图(r≥1)均有一个完美匹配.”故H含有一个完美匹配,因H是G的生成子图,当然H的完美匹配亦是G的完美匹配,从而完成证明.
注:定理“任意 r 正则二部图(r≥1)均有一个完美匹配.”之证明详见Gary Chartrand等著的《图论导引》第八章“匹配与分解”.
生成子图的定义是:如果图G的一个子图与G有相同的顶点集,那么该子图是图G的一个生成子图.

信息匹配(共5小题;每小题2分,满分10分)
Directions: Read the texts from a magazine article in which five people talked about their listening habits. For questions 6 4 to 68, match one of the speakers to one of the following statements (A to F ) given below. Note: there is one extra statement.
Mary Taylor:
My father looked at me disapprovingly when I talked to him about ideas that he didn’t agree with. He would often interrupt me in the middle of a sentence to tell me I was wrong. As a result of the childhood experience, I had difficulty concentrating when anyone in authority talked to me. I would concentrate on how I was coming across to the other person, not on what the person was saying.
Chris More:
My father used to frown (皱眉) when concentrating on something. I thought he was angry or upset with me until I later found out that he was only thinking about what he was doing. I certainly experienced some anxiety until I found this out. When I started conducting seminars(会议), I discovered that I frowned a lot while concentrating on what the talker was saying , and the attendees thought I was being critical of them.
Janet Smith:
I constantly tuned others out (不理睬)while they were talking and I couldn’t seem to break the habit . It upset me because I was having trouble at work listening to directions and paying attention during meetings. As it happened, my mother had been a nonstop talker who ignored my needs. To keep my own sanity(清醒), I had learned to shut her out of my consciousness. I became so good at tuning her out that I generalized this behavior ------ tuning other people out as well.
Lylian Mason:
I often feel victim in my interactions with my boss. I think he is the persecutor and I’m the victim. For example, late Thursday afternoon, my boss gave me a twenty-page project with graphs and numerical tables to type and finish by Monday at 10 a.m. I didn’t listen to the time he stated when he handed me the project. Instead, I was busy figuring out how I was going to get it down and finish the other work I had on my desk.
Jack Candison:
When I am with a group of people who are interested in the subject I am covering and are receptive to me, they are open to more material and ideas. The more important the subject is to them, the more listening involvement they get into. In other words, the more relevant my material is to their personal or professional goals, the more they listen to what I have to say and the less they tune me out.
64. __________ Mary Taylor
65. __________Chris More
66. __________Janet Smith
67. __________Lylian Mason
68. __________Jack Candison
A.It’s hard for me to change my bad habit of not listening to others.
B.The heavy workload worried me so much.
C.I gave people the impression that I’m being picky (挑剔的)
D.My boss listens to me carefully.
E.My father used to ignore me.
F.People are likely to listen more attentively while the subject is of interest to them.

全词匹配是将整个搜索词作为一个搜素单位(比如“中国文学”),返回的结果必须同时含有“中国文学”.
非全匹配(或者说“模糊匹配”)将搜索词拆分为“中”“国”“文”“学”,只要出现其中一个要素既可以返回结果,当然,一般会对结果作一定优化呈现,将要素结合得更紧密的结果优先呈现.

y=sinx-cosx
=√2(√2/2sinx-√2/2cosx)
=√2(cosπ/4sinx-sinπ/4cosx)
=√2sin(x-π/4)
-1≤sin(x-π/4)≤1
∴y最大值为√2,sin(x-π/4)=1 x-π/4=π/2+2kπ 即x=3π/4+2kπ
最小值为-√2,sin(x-π/4)=-1 x-π/4=-π/2+2kπ 即x=-π/4+2kπ k∈z

标准的反相比例放大电路是没有R2的,所以平衡电阻(不叫匹配电阻,谁教你的?)的大小就是R1//R4,
你现在这么一接,就成了R1//R2//R4了.你的结果没错,这个平衡电阻,其实就相当于输入端接地时,反相端总等效电阻,此时R4也是相当于接地的.这个结论你可以看童诗白的《模拟电子技术基础》第四版,P325

请阅读下列科技新闻的信息:
A. One of the biggest science stories last year was the research on stem cells announced by South Korean scientist Hwang Woo-suk. But now it appears that the research was false. In June, Mr. Hwang reported that he and his team at Seoul National University had created eleven new stem cell lines.
B. Another major science story last year came from the United States. On December twentieth, a federal judge ruled that teaching “intelligent design” in public schools is a violation of the United States Constitution.
C. There was also news last year about the American space program. The American space shuttle(航天飞机) returned to the skies in July. Discovery and its seven-member crew made the first shuttle flight in two and one-half years. NASA had suspended shuttle flights following the deadly explosion of the shuttle Columbia in 2003.
D. Avian influenza(禽流感) was also a major science story last year. The H5N1 virus appeared in birds in Europe for the first time. Yet the only known human cases of the disease have been in East Asia. There have been about one hundred forty confirmed cases of bird flu since 2003. About half the people have died.
E. The World Health Organization advises patients to take a combination of four drugs to treat tuberculosis(肺结核). These four antibiotics must be taken for about six months to cure the disease. Some people, however, take the drugs only until they feel better. Discontinuing treatment is a mistake.
F. The researchers began the study in January, 2002. They called it SMART---Strategies for Management of Anti-retroviral Therapy. The scientists reached more than ninety percent of the target before they halted(停止) new enrollments last month. The researchers tested all the people for the level of CD-four cells in their blood. The researchers divided the patients into two groups.
阅读以下与科技有关的信息卡,然后匹配信息卡和与之相关的科技新闻:
小题1: Card 1 : One group stayed on continuous anti-retroviral therapy. They took their medicines every day. The other took them periodically. They took the drugs only when their CD-four count fell below two hundred fifty cells per cubic millimeter of blood.
小题2: Card 2 : Judge John Jones said that intelligent design is not science. He said it is a version of Christianity. So to teach it in public schools violates the law that requires the separation of church and state. Supporters of intelligent design criticize the science of evolution.
小题3: Card 3 : Stem cells have the ability to grow into other cells. Science magazine published the report. The new lines were made from the eggs of eighteen women and skin cells from eleven other people.
小题4: Card 4 : Many of the victims had touched or been around infected farm birds. But health experts around the world began warning that the bird flu virus could change into a form that is passed from person to person.
小题5: Card 5 : That explosion was the result of damage done to Columbia during its launch. A piece of lightweight protective material fell off the shuttle’s external fuel container. The object hit the shuttle at a high rate of speed and made a hole in one of the wings. This permitted extremely hot gases to enter the shuttle and destroy the spacecraft as it returned to the earth.

首先next是干什么的.next[i]是指在(这里的i是1-n的)第i个匹配失败时,跳到前面的第几个字母.0就是跳过自身继续.
P= abaabcac
next 01122312
nextval 01021302
首先
acabaabaabcacabc
abaabcac
卡在2位上了
next[2]=1('b')
acabaabaabcacabc
abaabcac
卡1位,0,直接跳
acabaabaabcacabc
abaabcac
卡6位c,3,回到ab(a)xx
那么就是
acabaabaabcacabc
abaabcac
然后就匹配上了.

detector.detect(img_1,keypoints_1);//将img_1图像中检测到的特征点存储起来放在keypoints_1中
detector.detect(img_2,keypoints_2);//同理keypoints_1和keypoints_2里边存的就是两幅图像的特征点坐标

这是正则表达式()的作用:分组并且存储以备后面引用.
.*" 和 /b([a-z]+) 1b/gi
中(.*)和(【a-z】+)表示一个分组且存储了括号内一个表达式描述的字符.
一般用来引用重复出现的字符如 bb 可以这样([a-z])1 表示查找2个重复出现的字符.
1表示向前面括号内匹配的引用一下
g-表示在全局查找匹配
I:不区分大小写

张老师骑摩托车的速度为45千米/小时,学生步行速度为5KM/小时,学校与车站相距15KM,甲.乙两名学生从学校出发,要在50分钟内到车站,可以请张老师用摩托车送,但摩托车后座只能做1人,学生不能驾车也不能利用其他交通工具,你能设计一个方案,使两位学生能在最短的时间内赶到车站,并求出这个最短时间.
解:张老师骑摩托车的速度为每小时45千米,学生步行的速度是每小时5千米,学校与车站相距15千米.如果2名学生要在55分钟内从学校到车站,请张老师用摩托车送,但摩托车后座只能坐一个人,学生不能驾车,请你设计一个方案[学生只能步行或乘摩托车,上下摩托车的时间不计],使两名学生能在55分钟内全部到达车站,并用方程的有关知识说明理由.
方案就是一人先步行,一人乘车,然后乘车的人中途下车,车子回来接步行的人.最后二人一同到达.
要得二人同时到达,则二人步行的距离相同,乘车的距离也相同.
设第一人乘车距离是X,则步行距离是15-X.
第二人的步行距离也是15-X,车子从第一人的下车点到与第二人的相遇点的距离是:15-2(15-X)=2X-15
车子从出发到与第二人相遇的时间和第二人步行的时间相同.
所以有:(2X-15)/45=(15-X)/5
2X-15=9(15-X)
X=150/11
一共用的时间是:150/11/45+(15-150/11)/5=19/33小时=34.5分钟.
所以能在55分内到达.
