chord substitution

this set(3) Generate two articles of the respective word frequency vector;(4) Calculates the cosine similarity of two vectors, the greater the value, the more similar the representation.The code is implemented as follows: #余弦相似度算法 def cossimilarity(UL,P1,P2): Si = Getsameitem (ul,p1,p2) n = Len (SI) if n = = 0: Return 0 s = SUM ([Ul[p1][item]*ul[p2][item] for item in si]) Den1 = math.sqrt (SUM ([Pow (Ul[p1][item],2) for item in si])) Den2 = math.sqrt (SUM

Title Link: BZOJ-1006Problem analysisThis problem is a bare model of the minimum number of staining figures for a chord graph.The minimum coloring method of a string graph is to find out the perfect elimination sequence (MCS algorithm) of the chord graph, and then, in accordance with the perfect elimination sequence, backward forward from backward to the smallest color that each Dianran can dye.The number o

As we all know, the net is made up of nets (nonsense), the net is composed of something called mesh. If the mesh is small enough, you can catch a lot of fish; if the mesh is too large, the fish wi

ZOJ1015Test instructions Brief Description: Given an image without a direction, determine if there is a loop with a length greater than 3, and there is no chord on it (the edge of the connection ring on the different two points and not on the ring).The proposition is equivalent to the existence of a perfect elimination sequence for the graph.The so-called perfect elimination sequence: in the vi,vi+1,... vn VI and after the adjacent points with the vi

The idea of doing a problem： 1 chord chart, watched a weekend have wood there! Too weak, the algorithm perfectly eliminates the sequence according to the maximum potential algorithm (MCS) given by CDQ's ppt.

This method returns the inverse chord of the radian number. The Asin method returns the numeric value between 1 and 1, X-PI/2, and PI/2 radians. Returns Nan if the value of the number is outside this range. Grammar 1 Math.asin (x); The following are the details of the parameters: X: A number return value: Returns the inverse chord of the radian number.Example:

What if you have peer failures?After the example above, if N32 fail, but N80 finger table has not been updated, so that the query to the N16, it can not find N32, only N80, so that query will be lost.The workaround is to save R successor instead of just one successor,r is a value that the system can configure.So how big is R? So if there are a lot of errors, query can still arrive correctly.R=2log (N). W.h.p. = with high probabilityWhat to do if file fail is saved in nodeIf there is a missing fi

If the expression contains special characters, the Shell will replace it. For example, using a variable in double quotes is a substitution, and an escape character is also a substitution.As an example: #!/bin/bash A=ten echo- e "Value of A is $a \ n" Operation Result:Value of A is 10Here-e indicates the substitution of the escape character. If you do not use the-e option, it i

Command substitutionCommand substitution means that the shell can execute commands first, save the output temporarily, and output it where appropriate.Syntax for command substitution:' Command 'Note that it is an anti-quote , not a single quote, which is below the ESC key .In the following example, the command execution results are saved in a variable: #!/bin/bashdate = ' date ' who | WC -l ' echo

lowercase characters, easy to judge (purely according to user interests and hobbies);10. To cancel a variable, use unset: "unset variable name", for example, to cancel the configuration of myname:"Unset myname"Deletion, substitution, and substitution of variable contentsExample one: The lowercase path custom variable is configured to be the same as the path contentPath=${path}Echo $path/usr/kerberos/sbin:/
