title: Wavefront algorithm for area coverage
body: <p>I am wondering whether the <a href="http://www.societyofrobots.com/programming_wavefront.shtml" rel="nofollow">Wavefront algorithm</a> (or any other navigation algorithm), can be modified from trying to reach a a specific goal location to navigate to all reachable locations. </p>
  
  <p>Any other advice on different types of WaveFront algorithm would also be helpful. </p>
