There was a few years ago an article in DDJ about searching with Burroughs-Wheeler-Transform. The algo goes essentially like this: BWT your search space. All the strings with the same last letter will be together. Search for the first and last of them. They will give you index to second last letter. Now you can part your range according to second last letter in search string. Repeat 25. If you dont part you do a fuzzi. See the article http://www.ddj.com/articles/2003/0312/

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
