| Summary : Perform combinations and permutations on lists
|
Description :
Combinatorics is the branch of mathematics studying the enumeration,
combination, and permutation of sets of elements and the mathematical
relations that characterize their properties. As a jumping off point, refer
to:

This module provides a pure-perl implementation of nCk, nCRk, nPk, nPRk, !n
and n! (combination, multiset, permutation, string, derangement, and
factorial, respectively). Functional and object-oriented usages allow
problems such as the following to be solved:
* combine - nCk
http://mathworld.wolfram.com/Combination.html
\"Fun questions to ask the pizza parlor wait staff: how many possible
combinations of 2 toppings can I get on my pizza?\".
* derange - !n
http://mathworld.wolfram.com/Derangement.html
\"A derangement of n ordered objects, denoted !n, is a permutation in
which none of the objects appear in their \"natural\" (i.e., ordered)
place.\"
* permute - nPk
http://mathworld.wolfram.com/Permutation.html
\"Master Mind Game: ways to arrange pieces of different colors in a
certain number of positions, without repetition of a color\".
Object-oriented usage additionally allows solving these problems by calling
the /new() manpage with a *frequency* vector:
* string - nPRk
http://mathworld.wolfram.com/String.html
\"Morse signals: diferent signals of 3 positions using the two symbols -
and .\".
$o = Math::Combinatorics->new( count=>3 , data=>[qw(. -)] , frequency=>[3,3] );
while ( my AATTx = $o->next_multiset ) {
my $p = Math::Combinatorics->new( data=>\\AATTx , frequency=>[map{1} AATTx] );
while ( my AATTy = $p->next_string ) {
}
}
* multiset/multichoose - nCRk
http://mathworld.wolfram.com/Multiset.html
\"ways to extract 3 balls at once of a bag with 3 black and 3 white
balls\".
$o = Math::Combinatorics->new( count=>3 , data=>[qw(white black)] , frequency=>[3,3] );
while ( my AATTx = $o->next_multiset ) {
}
