This order is the optimal order but Waldico and Biehal keep switching by clicking "Calculate Optimal Route" (and the difference is enormous, from 317 km / 4u55 to 436 km / 6u10

8 years ago possible solution: always recalculate distance matrices, but it will give much more traffic to the Google Maps API
( matrices_up_to_date = false always)

8 years ago Also happens with the combination:
This order seems to be correct, but with clicking "Calculate Optimal Route" the locations 'tintelijn' and 'defosset' change place every click, although the difference in distance/time is not mentioned, there is a difference of 2 minutes.
When I first delete the Address, and then the Levering, and then click on "Calculate Optimal Route", the program crashes
[ void Form::process_result_distancematrix(QList<int>*) ] "Vlaspit" 0
[ void Form::process_result_distancematrix(QList<int>*) ] "Tintelijn" 2
ASSERT failure in QList<T>::at: "index out of range", file ../../QtSDK/Desktop/Qt/473/gcc/include/QtCore/qlist.h, line 456
The program has unexpectedly finished.
Sometimes, the optimal route is calculated, but shown incorrectly. Instead of following a perfect circle amongst 4 locations, it makes an X (resulting in a lot of unnecessary kilometers).
How to reproduce?
When you add the following locations:
Then you click on "Route tonen", then you click on "Route omdraaien".
If now you click on "Route optimaliseren", you get a very strange route.
It shows a route from 0 - 1 - 2 - 3 - 0:
While it should show a route from 0 - 1 - 3 - 2 - 0:
Please notice that the calculated "total distance" and "total time spent" is exactly the same for both screenshots, but the route shown (and the order in the QListWidget) is clearly different. Also, if we would compile a transportationlist, the lists of both instances will be different in the order of locations visited, but the total distance / time will be the same, also for stops in between (which is impossible).
The distance between 1 - 2 is much larger than between 1 - 3.
Possibility
Something goes wrong with the calculation of the distance matrix, with assigning the right markers to the correct rows of those matrices. Or maybe with reordering the markers in memory?
