title: Distance metric for algorithms
body: <p>I am currently working on a project in which I need to quantify the (dis)similarity between algorithms - that is, I have a few tens of algorithms that are used for the same purpose and I would like to quantify which ones are closest (i.e., more similar) to others, and which are truly 'novel'. </p>
  
  <p>Both my Google-Fu and my SO-Jutsu have failed me, so I would appreciate if anyone could shed a light on this. Does such a metric even exist?</p>
