Thanks. That makes sense. However, do I take it that you agree that application of such an algorithm (indeed, application of any algorithm, in any context) does not qualify as re[presenting any sort of 'intelligence'?Satnavs use a modified version of Dikstra's Shortest Path First algorithm, which is the foundation of the OSPF routing algorithm used by Autonomous Systems in the Internet. This is not really surprising, as the road system is a network too.
