1 2009-03-27 LEMON joins to the COIN-OR initiative

3 COIN-OR (Computational Infrastructure for Operations Research,

4 http://www.coin-or.org) project is an initiative to spur the

5 development of open-source software for the operations research

6 community.

8 2008-10-13 Version 1.0 released

10 This is the first stable release of LEMON. Compared to the 0.x

11 release series, it features a considerably smaller but more

12 matured set of tools. The API has also completely revised and

13 changed in several places.

15 * The major name changes compared to the 0.x series (see the

16 Migration Guide in the doc for more details)

17 * Graph -> Digraph, UGraph -> Graph

18 * Edge -> Arc, UEdge -> Edge

19 * source(UEdge)/target(UEdge) -> u(Edge)/v(Edge)

20 * Other improvements

21 * Better documentation

22 * Reviewed and cleaned up codebase

23 * CMake based build system (along with the autotools based one)

24 * Contents of the library (ported from 0.x)

25 * Algorithms

26 * breadth-first search (bfs.h)

27 * depth-first search (dfs.h)

28 * Dijkstra's algorithm (dijkstra.h)

29 * Kruskal's algorithm (kruskal.h)

30 * Data structures

31 * graph data structures (list_graph.h, smart_graph.h)

32 * path data structures (path.h)

33 * binary heap data structure (bin_heap.h)

34 * union-find data structures (unionfind.h)

35 * miscellaneous property maps (maps.h)

36 * two dimensional vector and bounding box (dim2.h)

37 * Concepts

38 * graph structure concepts (concepts/digraph.h, concepts/graph.h,

39 concepts/graph_components.h)

40 * concepts for other structures (concepts/heap.h, concepts/maps.h,

41 concepts/path.h)

42 * Tools

43 * Mersenne twister random number generator (random.h)

44 * tools for measuring cpu and wall clock time (time_measure.h)

45 * tools for counting steps and events (counter.h)

46 * tool for parsing command line arguments (arg_parser.h)

47 * tool for visualizing graphs (graph_to_eps.h)

48 * tools for reading and writing data in LEMON Graph Format

49 (lgf_reader.h, lgf_writer.h)

50 * tools to handle the anomalies of calculations with

51 floating point numbers (tolerance.h)

52 * tools to manage RGB colors (color.h)

53 * Infrastructure

54 * extended assertion handling (assert.h)

55 * exception classes and error handling (error.h)

56 * concept checking (concept_check.h)

57 * commonly used mathematical constants (math.h)
