title: Weighted A* on wikipedia
body: <p>I guess I find a problem on this wiki <a href="http://en.wikipedia.org/wiki/A%2a_search_algorithm" rel="nofollow">page</a>:</p>
  
  <p>I think the `</p>
  
  <blockquote>
    <p>have a cost of at most ε times</p>
  </blockquote>
  
  <p>in the <strong>Weighted A* algorithm</strong> part should be </p>
  
  <blockquote>
    <p>have a cost less than ε times</p>
  </blockquote>
  
  <p>instead.</p>
  
  <p>Because here it assumes ε > 1. But I am not sure about it, just want to listen anybody's opinion on this..</p>
  
  <p>Thank you for your help in advance :)</p>
