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).
***************************************************************************************
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.
 
***************************************************************************************
4.
 
And last but not the least, do not forget to check this site ;)
