Last change on this file since 11604 was 10324, checked in by gkronber, 11 years ago

#2106: changed methods for sorting in ObservableArray and ObservableList to use a stable sort (via Enumerable.OrderBy()). This is implemented as extension methods in HeuristicLab.Common. This implementation requires additional memory O(n).
The unit tests for tabu search had to be updated as the stable sort changes the results of the sample.
(minor bug fix in TestRandom)
