Support >= and <= constraints in NetworkSimplex (#219, #234) By default the same inequality constraints are supported as by Circulation (the GEQ form), but the LEQ form can also be selected using the problemType() function. The documentation of the min. cost flow module is reworked and extended with important notes and explanations about the different variants of the problem and about the dual solution and optimality conditions.

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)
