title: What is the current state of text-only compression algorithms?
body: <p>In honor of the <a href="http://prize.hutter1.net/" rel="noreferrer">Hutter Prize</a>, 
  what are the top algorithms (and a quick description of each) for text compression?</p>
  
  <p>Note: The intent of this question is to get a description of compression algorithms, not of compression programs.</p>
