A recent "Circle determines your future" is a fire, perhaps this means that people are the circle of animals. People will increase a lot of circles, and then the people in the circle more or less affect you, you in what kind of circle can finally become what kind of person. To a certain extent, the Chinese proverb "Jin

time I see him will tell me that I bought a discount Armani Jeans and so on. I feel that I am very successful now, and I am not the same as the people who speak home. I asked, what do you usually do? Did you learn something to read? He said no Ah, do not need to learn, has already done so.I said, "brother, where are you?" who are you compared to? A bunch of black cooks let you down? He said no, and he was better than his family. I mend the knife: "If you must put your life in the cook or the fa

Convex hull algorithm for planar circleWe've discussed this interesting question before: There are several circles on the plane that contain the intersection of all the convex sets of these circles. Based on the results discussed earlier, it is wrong to do a scan line directly by the center of the circle. We need to consider whether each point on the circle can be part of the convex hull.Howev

Feel that the last week did not pay attention to the electric circle this keyword. is too busy for the sake of, also have no time to their own electricity business district Sina Blog watering. Baidu today a bit, surprised, there are nearly 7 independent domain name string to the Baidu home page. According to my consistent thinking, if a keyword has a bid advertising, or the first few pages of independent domain name appear more, it shows that this key

Source: hdoj 1700 Mathematical Proof] If R is the circle radius, A, B, and C are the angles of triangles, A/Sina = B/sinb = C/sinc = 2R is obtained from the sine theorem.Therefore, A + B + C = 2R (SINA + sinb + sinc). When r determines that the circumference A + B + C is the largest, the sum is the maximum of SINA + sinb + sinc.Set y = SINA + sinb + sinc, first fixed angle,Y = SINA + sinb + sinc = SINA + 2sin (B + C)/2) Cos (B-C)/2)= SINA + 2cos (A/2

Didn't want to learn ... So today I met a big naked question ... Example: bzoj2823 to find the smallest circle covering n points. The pseudo code is as follows: Randomize all points, set to (x[1],y[1])... (X[n],y[n]) start to set the center to x[1], the radius is set to 0 forI=2 toN If the I point is within the current circle, skip//so I point on the circumference of the point 1th and I as the diameter of

Main topicGive some points on the plane to find out how many points a unit circle can cover.IdeasData range 300, but no use, multiple sets of data is to card o ( n 3 ) , but the constant optimization of the better words in the POJ can be, but BZ still can't live. We need to find a O( n 2 Log N) The practice.The practice is to enumerate each point and make a single circle

I am not a senior either. I can't talk about it, but I want to say it again, so I simply put it bluntly.As the blog circle becomes increasingly prominent and registrants soar, I am afraid all new users will post actively and want to attract your attention. I hope you will reply to the discussion a lot, I think this is the psychological status of every new employee, but some may be because they have not accumulated some experience, but they also want t
