## Solved: How do I generate all permutations of a list?

Question: How do I generate all the permutations of a list? For example: Best Answer: Use itertools.permutations from the standard library: Adapted from here is a demonstration of how itertools.permutations might be implemented: A couple of alternative approaches are listed ...

## Resolved: Array combinatorics in javascript, It’s wrong?

Question: I have created this script due to the need to perform unique combinations when I receive n number of arrays. It works, however when I want to store in a final array it writes something different. Answer: You’re saving ...

## Resolved: out-of-core/external-memory combinatorics in python

Question: I am iterating the search space of valid Python3 ASTs. With max recursion depth = 3, my laptop runs out of memory. My implementation makes heavy use of generators, specifically ‘yield’ and itertools.product(). Ideally, I’d replace product() and the ...

## Resolved: Create a list of combinations recursively

Question: I am trying to implement a combination method using recursion. I have already done it using a for loop but want to approach it via recursion. The method gets two inputs and creates all possible combinations. It is supposed ...

## Resolved: Calculating the nth combination of a set of sequential numbers

Question: I have a number n that my program uses to represent a list of natural numbers of size n: The lists always begin with 0 and their elements appear in sequential order with no numbers skipped. The last element ...

## Resolved: How to generate all permutations of 1 and 0 bits of a given size in Swift

Question: I would like to be able to generate an array of all possible permutations of a Bool (true/false or 1/0) of a given size n, in Swift. For example, given n=2 the result of calling generate(2) would be I ...

## Resolved: Combinatorics in python numpy

Question: I’d like to write a single function that outputs all the possible combinations of 2 matrixes: However when passed: It outputs: How can I make it work? I would like to keep it automatic, not to simply pass (args, ...

## Resolved: How to find a list of all possible decompositions of a list into chunks of size bigger than 2

Question: For a given N, I have a list of all numbers from 0 to N-1 and I want to find a list of all possible decompositions into lists of sizes two or higher, without repetitions. For example, for N=4 ...

## Resolved: Recursively choose K items from N , until empty

Question: An example illustrates it best Starting with a list of N unique items = [‘A’,’B’,’C’,’D’,’E’] Pick k=2 items Here we have Python implementation to show the number of possible combinations: Now, for each of the 10 combinations, imagine taking ...
