kpeter [Thu, 28 Feb 2008 02:54:27 +0000] rev 2581
Query improvements in the min cost flow algorithms.
- External flow and potential maps can be used.

- CycleCanceling also provides dual solution (node potentials).
- Doc improvements.

kpeter [Mon, 18 Feb 2008 03:34:16 +0000] rev 2577
Add a cost scaling min cost flow algorithm.
Add a cost scaling algorithm, which is performing generalized
push-relabel operations. It is almost as efficient as the capacity
scaling algorithm, but slower than network simplex.
kpeter [Mon, 18 Feb 2008 03:32:56 +0000] rev 2576
Improvements in MinCostFlow and MinCostMaxFlow.
Main changes:
- MinCostMaxFlow also provides dual solution.
- Change the name of private members to start with "_".
- Change the name of function parameters not to start with "_".
- Remove unnecessary documentation for private members.
- Doc improvements.
kpeter [Mon, 18 Feb 2008 03:32:06 +0000] rev 2575
Major improvements in NetworkSimplex.
Main changes:
- Use -potenital[] instead of potential[] to conform to the usual
terminology.
- Use function parameter instead of #define commands to select pivot rule.
- Use much faster implementation for the candidate list pivot rule.
It is about 5-20 times faster now.
- Add a new pivot rule called "Limited Search" that is a modified
version of "Block Search". It is about 25 percent faster on rather
sparse graphs.
- By default "Limited Search" is used for sparse graphs and
"Block Search" is used otherwise. This combined method is the most
efficient on every input class.
- Change the name of private members to start with "_".
- Change the name of function parameters not to start with "_".
- Remove unnecessary documentation for private members.
- Many doc improvements.
