title: How to find the closest turtle(s)?
body: <p>NetLogo command <code>distance &lt;agent&gt;</code> can be used to find the distance of a turtle from another turtle.<br>
  However, I am looking for each turtle to be able to find the turtle(s) with the smallest sum of [distance from it + price(a turtle variable)]. How can I get the turtles to do that? </p>
