Changes in Makefile_insert http://src.iws.cs.ovgu.de/source/rss/inkscape/src/libvpsc/Makefile_insert en Copyright 2005 Java remove files that interface through C with libvpsc, we are using C++ so... /inkscape/src/libvpsc/Makefile_insert - d3cb948619594a5b8bf72042fe73b3a542c7fb97 Johan B. C. Engelen <j.b.c.engelen@alumnus.utwente.nl> drop more missing files from autoconf /inkscape/src/libvpsc/Makefile_insert - fcc5467c5495f9ca3b67a4b6bcdf061765f42c61 keescook <keescook@users.sourceforge.net> Previously graph layout was done using the Kamada-Kawai layout algorithm implemented in Boost. I am replacing this with a custom implementation of a constrained stress-majorization algorithm. The stress-majorization algorithm is more robust and has better convergence characteristics than Kamada-Kawai, and also simple constraints can be placed on node position (for example, to enforce downward-pointing edges, non-overlap constraints, or cluster constraints). Another big advantage is that we no longer need Boost. I've tested the basic functionality, but I have yet to properly handle disconnected graphs or to properly scale the resulting layout. This commit also includes significant refactoring... the quadratic program solver - libvpsc (Variable Placement with Separation Constraints) has been moved to src/libvpsc and the actual graph layout algorithm is in libcola. /inkscape/src/libvpsc/Makefile_insert - 1ec681f88b68c6186b267afcce12c7fd667cc9f8 tgdwyer <tgdwyer@users.sourceforge.net>
