问题 How can I implement a bipartite matching algorithm (probably based on a max-flow algorithm) in C or C++ ? To be specific, I have this input in a file: (1,3) (1,5) (2,5) (M,F) --> where M represents id of MALE and F is id of FEMALE. I need to find the maximum number of matches and show matched couples. Like: matches: 1&3 , 2&5 I have read in some books I can base this problem on a "maximum flow in a network" algorithm, but I couldn't find any specific info other than the sentence "this problem

问题 How to selectively disable atom from creating a matching single quote and and backtick? This helps in programming in Scheme. I tried Settings>Package>Bracket Matcher, if I disable Autocomplete bracket then it also disables matching brackets and matching double quotes. I want matching brackets and matching double quotes but not matching single quotes. EDIT: This feature is now available in Atom. 回答1: The feature that you want is now available. Just delete the quotes from the Autocomplete

问题 I have a list of strings containing about 7 million items in a text file of size 152MB. I was wondering what could be best way to implement the a function that takes a single string and returns whether it is in that list of strings. 回答1: Are you going to have to match against this text file several times? If so, I'd create a HashSet<string> . Otherwise, just read it line by line (I'm assuming there's one string per line) and see whether it matches. 152MB of ASCII will end up as over 300MB of

问题 I want to compare two columnn -- Description and Employer . I want to see if any keywords in Employer are found in the Description column. I have broken the Employer column down to words and converted to a list. Now I want to see if any of those words are in the corresponding Description column. Sample input: print(df.head(25)) Date Description Amount AutoNumber \ 0 3/17/2015 WW120 TFR?FR xxx8690 140.00 49246 2 3/13/2015 JX154 TFR?FR xxx8690 150.00 49246 5 3/6/2015 CANSEL SURVEY E PAY 1182.08

问题 Wanted Attached is a snip picture of what I want to do. I have one column that lists all the options, and on the second column some items. For each item I want the user to physically select a cell and I can then use that selection as the match to the item. For example if the use click on "user1" then I need to populate cell D4 with text "user1". How can I achieve this? Thanks! 回答1: On the code for the worksheet from which you want to use the selection: Private Sub Worksheet_SelectionChange

问题 Is there a way to join two arrays based upon a same value in a key? As an example in MySQL you can left join two tables when two fields have the same value in it. The first array called 'phoneArr' is one with a person_id and a phone number The second array called 'clientDate' is one with a person_id and a appointment date. Here are the arrays: $phoneArr = array(); $phoneArr[0]['person_id'] = "123456"; $phoneArr[0]['phone'] = "555-2222"; $phoneArr[1]['person_id'] = "7654321"; $phoneArr[1][

问题 In order to align the intensity values of two grayscale Images (as a first step for further processing) I wrote a Java method that: converts the bitmaps of the two images into two int[] arrays containing the bitmap's intensities (I just take the red component here, since it's grayscale, i.e. r=g=b ). public static int[] bmpToData(Bitmap bmp){ int width = bmp.getWidth(); int height = bmp.getHeight(); int anzpixel = width*height; int [] pixels = new int[anzpixel]; int [] data = new int[anzpixel

问题 So using the Matching Package (Link to package here) We can work through a modified GenMatch example. library(Matching) data(lalonde) #introduce an id vaiable lalonde$ID <- 1:length(lalonde$age) X = cbind(lalonde$age, lalonde$educ, lalonde$black, lalonde$hisp, lalonde$married, lalonde$nodegr, lalonde$u74, lalonde$u75, lalonde$re75, lalonde$re74) BalanceMat <- cbind(lalonde$age, lalonde$educ, lalonde$black, lalonde$hisp, lalonde$married, lalonde$nodegr, lalonde$u74, lalonde$u75, lalonde$re75,
