combinatorics

问题 I'm trying to build a Javascript function that takes as an input: array of players e.g. ["player1","player2","player3","player4"] (probably only equal number of players) and dynamically creates an array for a tournament design based on the following rules: each player partners no more than once with the same player every player has an equal amount of total matches the outputs would be an array containing arrays of matches with four entries each e.g. [player1, player2, player3, player4] stands

问题 I am trying to get all possible ways to distribute n candies among k children. For instance, according to stars-and-bars formula, number of ways to distribute 96 candies among 5 children is 100! / (96!*4!) = 3 921 225 tuples of all possible permutations of size 5. list2 = [item for item in it.product(range(97), repeat = 5) if sum(item) == 96] My PC seems to overwhelmed by complexity. Each tuple consumes 24*5 = 120 bytes of memory. This results in 921 225 * 120 = 470547000 bytes or 450 mb.

问题 My goal is to create a part of code that would generate all possible combinations without duplicates (combinations with same elements, no matter what their sequence is) with data from a JSON file. My JSON file looks like this: [ { "COLLECTION": "Assault", "WEAPON": "SG 553", "SKIN": "Tornado", "GRADE": "Consumer Grade" }, { "COLLECTION": "Assault", "WEAPON": "UMP-45", "SKIN": "Caramel", "GRADE": "Consumer Grade" }, { "COLLECTION": "Vertigo", "WEAPON": "Five-SeveN", "SKIN": "Candy Apple ",

问题 (This is inspired by another question marked as a duplicate. I think it is an interesting problem though, although perhaps there is an easy solution from combinatorics, about which I am very ignorant.) Problem For a vector of length n , where n mod 2 is zero, find all possible ways to partition all elements of the vector into pairs, without replacement, where order does not matter. For example, for a vector c(1,2,3,4) : list(c(1,2), c(3,4)) list(c(1,3), c(2,4)) list(c(1,4), c(2,3)) My

问题 I am looking to find and print all possible combinations of the set (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) of length 5. There should be 13 choose 5 combinations (6188) because order does NOT matter, and repetition is allowed. I found this code and was using it: from itertools import product for item in product([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12], repeat=5): print(item) However, this is not printing all 6188 combinations. Trying to figure out how to tweak the code so it spits out
