Let\'s define custom operators - let it be ++,equals :- op(900, yfx, equals). :- op(800, xfy, ++). And fact:
I\'m working on a project for fun and I need an algorithm to do as follows: Generate a list of numbers of Length n which add up to x
I have a population of 50 ordered integers (1,2,3,..,50) and I look for a generic way to slice it \"n\" ways (\"n\" is the number of cutoff points ranging from 1 to 25) that maintains the order of the
Suppose we have a table of numbers like this (we can assume it is a square table): 202134 511489 1512171711
There is a mapping of characters, like so: $replacements = array( array(\'a\', \'b\'), // a => b array(\'a\', \'c\'), // a => c
I need to create a function (in R) which: - given N possible variables to attribute weights to; - creates all possible permuati开发者_Python百科ons of weights (summing to 100%);
I have an alphabet array with 26 characters A..Z . I am searching for a performant algorithm that list开发者_运维技巧s all permutations that fill an array of length X without any repeating characters
I\'m stuck on a small but tricky problem since yesterday. What I have is a (possibly infinitely) nested list like this:
For example, rankpermutation 0abc 1acb 2bac 3bca 4cab 5cba So, if one asks give me permutation with rank 4, the answer is cab.Pls give the java code for this progra开发者_开发百科mI made it at a fi
I think this is a common combinatorics problem, but I can\'t seem to find a name for it开发者_开发技巧 or any material about it. I am doing this in Python and numpy, but if there is a fast matrix meth
