 ### What is preference elicitation?
 Most real-world decisions must reconcile multiple, competing objectives. In buying a car, you might be concerned about cost, reliability, and performance, but before you can make a decision, you must establish the relative importance of these goals. A common mathematical approach to this problem is to define weights for each of these objectives. Although you might have a ballpark intuition for the weights, it is difficult to set them in a repeatable and defendable manner.
