How gps finds the best way

  1. Sep 20, 2014 #1
    Hi there,

    I am not sure if it's the right place to ask the question.
    My question is how the GPS chooses the best way.
    I mean where I can find something about its idea

    Once the two end points are defined, this becomes an Operations Research optimization problem. You may want the shortest path, or you may want the fastest path (based on speed limits for each segment), or some other criterion. Operations Research is a well defined field dealing with such problems.
