Version history

Initial release

Major enhancement:  Implementation of time-series min-cost-max-flow.

Several minor bugfixes: e.g., GUI now passes correct alpha value to PageRank.

Fixed configuration issue between the python libraries py2exe and elementtree that caused python-based functions (betweenness centrality, etc.) to fail with ImportError message.

Approximate shortest-path betweenness centrality allows faster computation of this metric

Approximate current flow betweenness centrality allows faster computation of this metric; function also uses sparse matrices for lower RAM requirements

Network flow functions updated to LEMON version 1.2.2

Updates to manual and tutorial dataset

Updated python and python packages, including NetworkX to version 1.6.

Current flow betweenness centrality subset also now uses sparse matrices for lower RAM requirements. (Note that there is no approximate function for current flow betweenness centrality subset, so it is still slow for large datasets).

Updated python and python packages, including NetworkX to version 1.8dev.

Updated Hexsim-based functions to Hexsim version 2.5.1, which improves conversion of .asc input file  to hxn file.

Added support for locales (e.g., areas in Europe) that use a comma instead of a period as decimal separator.

Updated LEMON to version 1.3.

Turned off arc mixing in network flow functions to resolve potential division by zero error.

Updated NetworkX to version 1.8.1.

Updated Hexsim-based functions to Hexsim version 2.5.3.

Updated NetworkX to version 1.9.

Updated Hexsim-based functions to Hexsim version 3.0.4.
