Support real types + numerical stability fix in NS (#254) - Real types are supported by appropriate inicialization. - A feature of the XTI spanning tree structure is removed to ensure numerical stability (could cause problems using integer types). The node potentials are updated always on the lower subtree, in order to prevent overflow problems. The former method isn't notably faster during to our tests.

2008-10-13 Version 1.0 released



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

	release series, it features a considerably smaller but more

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

	changed in several places.



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

          Migration Guide in the doc for more details)

          * Graph -> Digraph, UGraph -> Graph

          * Edge -> Arc, UEdge -> Edge

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

	* Other improvements

	  * Better documentation

	  * Reviewed and cleaned up codebase

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

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

	  * Algorithms

       	    * breadth-first search (bfs.h)

       	    * depth-first search (dfs.h)

       	    * Dijkstra's algorithm (dijkstra.h)

       	    * Kruskal's algorithm (kruskal.h)

    	  * Data structures

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

       	    * path data structures (path.h)

       	    * binary heap data structure (bin_heap.h)

       	    * union-find data structures (unionfind.h)

       	    * miscellaneous property maps (maps.h)

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

          * Concepts

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

              concepts/graph_components.h)

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

	      concepts/path.h)

    	  * Tools

       	    * Mersenne twister random number generator (random.h)

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

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

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

       	    * tool for visualizing graphs (graph_to_eps.h)

       	    * tools for reading and writing data in LEMON Graph Format

              (lgf_reader.h, lgf_writer.h)

            * tools to handle the anomalies of calculations with

	      floating point numbers (tolerance.h)

            * tools to manage RGB colors (color.h)

    	  * Infrastructure

       	    * extended assertion handling (assert.h)

       	    * exception classes and error handling (error.h)
