1. A computerised method of selecting a route or routes through a network which takes account of previous occasions when portions of that network have been used, the method comprising:
- associating each portion of the network with a cost function;
varying the cost function associated with each portion of the network based on a familiarity level indicative of how often each portion of the network has previously been used wherein said familiarity level is reduced using an exponential decay with time; and
searching the network for a route or routes with a low overall cost.

19. A non-transitory computer media carrying processor code which when implemented on a processor causes said processor to carry out a method for selecting a route or routes through a network which takes account of previous occasions when portions of that network have been used, the method comprising:
-
associating each portion of the network with a cost function; varying the cost function associated with each portion of the network based on a familiarity level indicative of how often each portion of the network has previously been used wherein said familiarity level is reduced using an exponential decay with time; and searching the network for a route or routes with a low overall cost.

20. Apparatus for selecting a route or routes through a network which takes account of previous occasions when portions of that network have been used, the apparatus comprising a processor configured to:
-
associate each portion of the network with a cost function; vary the cost function associated with each portion of the network based on a familiarity level indicative of how often each portion of the network has previously been used wherein said familiarity level is reduced using an exponential decay with time; and search the network for a route or routes with a low overall cost.
