title: Algorithm to Rate Objects with Numerous Comparisons
body: <p>Lets say I have a list of 500 objects. I need to rate each one out of 10.</p>
  
  <p>At random I select two and present them to a friend. I then ask the friend which they prefer. I then use this comparison (ie OBJECT1 is better than OBJECT2) to alter the two objects' rating out of ten.</p>
  
  <p>I then repeat this random selection and comparison thousands of times with a group of friends until I have a list of 500 objects with a reliable rating out of ten.</p>
  
  <p>I need to figure out an algorithm which takes the two objects current ratings, and alters them depending on which is thought to be better...</p>
