Hello,
Our application interfaces with MapPoint to do some routing and then optimizing the stops within that route. What I have noticed is that when we send the exact same stops to MapPoint we get a different end result for the stops after optimizing.

To make sure it was not our application I created an Excel file and imported those stops and routed/optimized them and got different results each time. Does anyone else have this problem? Any ideas on settings that could affect this?

Thanks.

Are all of the routing parameters EXACTLY the same?

Eg. route type (this is set on a waypoint-by-waypoint basis), speed, preferences, etc.

Doing a route "clear" will clear many of them which you would expect to be sticky (road speeds and/or road preferences come to mind).

Yes, I opened up two MapPoint applications and followed the same steps both times. Each time I optimized the route I would get different results. Before optimizing I did check the route options and they were set the same.

Thanks.

It is probably the heuristics in the "Optimize" function then.

Optimize does not calculate all options - only a tiny fraction in fact.
(to check all would take years if not millions of years in many cases)
