#2215: Fixed a couple of bugs in the BottomUpSimilarityCalculator:

  • the child sequences of matching nodes were not sorted in the same way (one was using StringComparison.Ordinal, the other the default)
  • when creating the mapping it is necessary to walk the nodes of the first tree in decreasing height order (not level-order as the author claims)

#2215: Fixed incorrect namespace of the BottomUpSimilarityCalculator. Changed signature of ComputeBottomMapping method to take tree nodes as arguments rather than trees, because we should be able to compute the bottom-up distance for any two subtrees. Added internal diversity calculator based on the bottom-up distance, which computes the average diversity of all the nodes inside a tree individual.

#2215: Realized that "Height" in the paper might actually refer to the subtree depth (and not it's level in the tree). Changed code according to this interpretation as it makes more sense and seems to produce the correct results.

#1772: Separated tree distance calculations in different classes which implement a new interface called IDistanceCalculator. The isomorphic tree distance calculates the distance based on the maximum common subtree between two symbolic expression trees, and the bottom-up tree distance returns a value based on the number of matching pairs of nodes in a bottom-up mapping. Introduced the distance calculator as a parameter in the SimilarityCalculator operator so that the diversity analyzer can use either of the two distances.
