QAP visualization does not render weights matrices correctly

Reported by: abeham Owned by: abeham
Priority: medium Milestone: HeuristicLab 3.3.7
Component: Problems.QuadraticAssignment.Views Version: 3.3.7
Keywords: Cc:

Description

Weight matrices sometimes are not fully connected. When the weights matrix is transformed into a dissimilarity matrix the absence of a weight is encoded as a distance nevertheless.

  • added NaN check to MultidimensionalScaling
  • fixed a bug in StressFitness and now ignore distance to self
  • changed transformation of the weights matrix to a dissimiliarity matrix (set entries to NaN when weight was 0)
  • swapped weights and distance matrix for the els19

Reviewed the code changes of r7416, but I must admit that I didn't understand their effects in full detail (especially changes in the MultiDimensionalScaling).
