Dear Socnet mailing list members.

Pajek and PajekXXL 3.13 are now available.

Among other small improvements and speed-ups (see history) version 3.13 brings:

***************************************************************************************
1.

Pathfinder algorithm - removing lines of a weighted network where values of lines are dissimilarities.
Network / Create New Network / Transform / Reduction / Pathfinder*
Only lines which do not violate the triangle inequality are kept.
It can be applied to medium sized networks (networks with up to approx. 10000 vertices).
Details:
http://en.wikipedia.org/wiki/Pathfinder_network
***************************************************************************************
2.

Another centrality measure added to Pajek and PajekXXL: Laplacian Centrality.
It can be used for huge networks as well. For definition see:

***************************************************************************************
3.
Kamada-Kawai optimization (especially Separate Components suboption)
speeded up significantly.
