NAME
LCS::BV - Bit Vector (BV) implementation of the Longest Common
Subsequence (LCS) Algorithm
SYNOPSIS
use LCS::BV;
$alg = LCS::BV->new;
@lcs = $alg->LCS(\@a,\@b);
ABSTRACT
LCS::BV implements Algorithm::Diff using bit vectors and is faster in
most cases, especially on strings with a length shorter than the used
wordsize of the hardware (32 or 64 bits).
DESCRIPTION
CONSTRUCTOR
new()
Creates a new object which maintains internal storage areas for the
LCS computation. Use one of these per concurrent LCS() call.
METHODS
LLCS(\@a,\@b)
Return the length of a Longest Common Subsequence, taking two
arrayrefs as method arguments. It returns an integer.
LCS(\@a,\@b)
Finds a Longest Common Subsequence, taking two arrayrefs as method
arguments. It returns an array reference of corresponding indices,
which are represented by 2-element array refs.
EXPORT
None by design.
