NAME

LCS::BV - Bit Vector (BV) implementation of the Longest Common Subsequence (LCS) Algorithm

html

SYNOPSIS

  use LCS::BV;

  $lcs = LCS::BV::LCS($a,$b);

ABSTRACT

LCS::BV implements the Longest Common Subsequence (LCS) Algorithm and is more than double as fast (Jan 2016) than Algorithm::Diff::LCSidx().

DESCRIPTION

This module is a port from the Perl5 module with the same name.

The algorithm used is based on

H. Hyyroe. A Note on Bit-Parallel Alignment Computation. In
M. Simanek and J. Holub, editors, Stringology, pages 79-87. Department
of Computer Science and Engineering, Faculty of Electrical
Engineering, Czech Technical University, 2004.

METHODS

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.
