e65a102527 Remove unit Laz_AVL_Tree, a copy of unit AVL_Tree. Not needed with FPC 3.2.x. 2023-07-07 17:39:03 +03:00

fcd8b1721b LvlGraph: Speed up TMinXGraph. In StoreAsBest only update nodes that changed. This massively speeds up big graphs with several thousand (including hidden) nodes, were StoreAsBest did always copy all those nodes. 2022-01-10 14:33:03 +01:00

42d6e0bc85 LvlGraph: Ensure work was done, or quit. No endless loop. 2022-01-10 14:33:03 +01:00

abb908d498 LvlGraph: Reduce "zero-run" switching in favour of shuffling. Do one final big zero-run, if needed. 2022-01-10 14:33:03 +01:00

f33a15738a LvlGraphOptions: TMinXGraph refactor. Store only nodes that need to be switched in SameSwitchDiffPairs (SwitchDiff > 0 would create new crossings). 2022-01-10 14:33:03 +01:00
Martin
52679121ad LvlGraph: Only shuffle small bits of the graph. This allows to continue on the existing result, but can switch nodes not found by the normal switching. 2022-01-10 14:23:23 +01:00

e9367141f8 TLvlGraph: Improve MinimizeCrossings. Switch pairs even if they have SwitchDiff=0 
A pair with "SwitchDiff=0" may block surrounding nodes from being switched. After switching, one of the changed neighbouring pairs may be able to reduce further crossings.

e800a738ad Copy AVL_Tree from FPC trunk and replace classes in AvgLvlTree and in CodetoolsStructs with it. 
The unit in FPC packages will be used directly later.
