\brief Graph structures implemented in LEMON.
28 28

	
29 29
The implementation of combinatorial algorithms heavily relies on
30 30
efficient graph implementations. LEMON offers data structures which are
31 31
planned to be easily used in an experimental phase of implementation studies,
32 32
and thereafter the program code can be made efficient by small modifications.
33 33

	
34 34
The most efficient implementation of diverse applications require the
35 35
usage of different physical graph implementations. These differences
36 36
appear in the size of graph we require to handle, memory or time usage
37 37
limitations or in the set of operations through which the graph can be
38 38
accessed.  LEMON provides several physical graph structures to meet
39 39
the diverging requirements of the possible users.  In order to save on
40 40
running time or on memory usage, some structures may fail to provide
41 41
some graph features like arc/edge or node deletion.
42 42

	
43 43
Alteration of standard containers need a very limited number of
44 44
operations, these together satisfy the everyday requirements.
45 45
In the case of graph structures, different operations are needed which do
46 46
not alter the physical graph, but gives another view. If some nodes or
47 47
arcs have to be hidden or the reverse oriented graph have to be used, then
48 48
this is the case. It also may happen that in a flow implementation
49 49
the residual graph can be accessed by another algorithm, or a node-set
50 50
is to be shrunk for another algorithm.
51 51
LEMON also provides a variety of graphs for these requirements called
52 52
\ref graph_adaptors "graph adaptors". Adaptors cannot be used alone but only
53 53
in conjunction with other graph representations.
54 54

	
55 55
You are free to use the graph structure that fit your requirements
56 56
the best, most graph algorithms and auxiliary data structures can be used
57
with any graph structures.

96 99
This group describes map adaptors that are used to create "implicit"
97 100
maps from other maps.
98 101

	
99 102
Most of them are \ref lemon::concepts::ReadMap "read-only maps".
100 103
They can make arithmetic and logical operations between one or two maps
101 104
(negation, shifting, addition, multiplication, logical 'and', 'or',
102 105
'not' etc.) or e.g. convert a map to another one of different Value type.
103 106

	
104 107
The typical usage of this classes is passing implicit maps to
105 108
algorithms.  If a function type algorithm is called then the function
106 109
type map adaptors can be used comfortable. For example let's see the
107
usage of map adaptors with the \c digraphToEps() function.

      return Color(0.5, 0.0, 0.5);
112 115
    } else if (deg == 1) {
113 116
      return Color(1.0, 0.5, 1.0);
114 117
    } else {
115 118
      return Color(0.0, 0.0, 0.0);

124 127
    .run();
125 128
\endcode
126 129
The \c functorToMap() function makes an \c int to \c Color map from the
127
\e nodeColor() function. The \c composeMap() compose the \e degree_map
130
\c nodeColor() function. The \c composeMap() compose the \c degree_map
128 131
and the previously created map. The composed map is a proper function to
129 132
get the color of each node.
130 133

	
131 134
The usage with class type algorithms is little bit harder. In this
132 135
case the function type map adaptors can not be used, because the
133 136
function map adaptors give back temporary objects.
134 137
\code
135 138
  Digraph graph;
136 139

	
137 140
  typedef Digraph::ArcMap<double> DoubleArcMap;
138 141
  DoubleArcMap length(graph);
139 142
  DoubleArcMap speed(graph);
140 143

142 145
  TimeMap time(length, speed);

145 148
  dijkstra.run(source, target);
146 149
\endcode
147 150
We have a length map and a maximum speed map on the arcs of a digraph.
148 151
The minimum time to pass the arc can be calculated as the division of
149 152
the two maps which can be done implicitly with the \c DivMap template
150 153
class. We use the implicit minimum time map as the length map of the
151 154
\c Dijkstra algorithm.

This group describes the algorithms for finding maximum flows and
221 222
feasible circulations.
222 223

	
223 224
The maximum flow problem is to find a flow between a single source and
224 225
a single target that is maximum. Formally, there is a \f$G=(V,A)\f$
225 226
directed graph, an \f$c_a:A\rightarrow\mathbf{R}^+_0\f$ capacity
226 227
function and given \f$s, t \in V\f$ source and target node. The
227 228
maximum flow is the \f$f_a\f$ solution of the next optimization problem:
228 229

	
229 230
\f[ 0 \le f_a \le c_a \f]
230 231
\f[ \sum_{v\in\delta^{-}(u)}f_{vu}=\sum_{v\in\delta^{+}(u)}f_{uv}
231 232
\qquad \forall u \in V \setminus \{s,t\}\f]
232 233
\f[ \max \sum_{v\in\delta^{+}(s)}f_{uv} - \sum_{v\in\delta^{-}(s)}f_{vu}\f]
233 234

	
234 235
LEMON contains several algorithms for solving maximum flow problems:
235 236
- \ref lemon::EdmondsKarp "Edmonds-Karp"
236 237
- \ref lemon::Preflow "Goldberg's Preflow algorithm"
237 238
- \ref lemon::DinitzSleatorTarjan "Dinitz's blocking flow algorithm with dynamic trees"
238 239
- \ref lemon::GoldbergTarjan "Preflow algorithm with dynamic trees"
239 240

	
240 241
In most cases the \ref lemon::Preflow "Preflow" algorithm provides the
241 242
fastest method to compute the maximum flow. All impelementations
242 243
provides functions to query the minimum cut, which is the dual linear
243 244
programming problem of the maximum flow.

\f$c_a:A\rightarrow\mathbf{R}^+_0\f$ capacity function. The minimum
269 269
cut is the \f$X\f$ solution of the next optimization problem:
270 270

	
271 271
\f[ \min_{X \subset V, X\not\in \{\emptyset, V\}}
272 272
\sum_{uv\in A, u\in X, v\not\in X}c_{uv}\f]
273 273

	
274 274
LEMON contains several algorithms related to minimum cut problems:
275 275

	
276 276
- \ref lemon::HaoOrlin "Hao-Orlin algorithm" to calculate minimum cut
277 277
  in directed graphs
278 278
- \ref lemon::NagamochiIbaraki "Nagamochi-Ibaraki algorithm" to
279 279
  calculate minimum cut in undirected graphs
280 280
- \ref lemon::GomoryHuTree "Gomory-Hu tree computation" to calculate all
281 281

317 316
This group contains algorithm objects and functions to calculate
318 317
matchings in graphs and bipartite graphs. The general matching problem is
319 318
finding a subset of the arcs which does not shares common endpoints.
320 319

	
321 320
There are several different algorithms for calculate matchings in
322 321
graphs.  The matching problems in bipartite graphs are generally
323 322
easier than in general graphs. The goal of the matching optimization
324 323
can be the finding maximum cardinality, maximum weight or minimum cost
325 324
matching. The search can be constrained to find perfect or
326 325
maximum cardinality matching.

503 490

	
504 491
The purpose of the classes in this group is fourfold.
505 492

	
506 493
- These classes contain the documentations of the concepts. In order
507 494
  to avoid document multiplications, an implementation of a concept
508 495
  simply refers to the corresponding concept class.
509 496

	
510 497
- These classes declare every functions, <tt>typedef</tt>s etc. an
511 498
  implementation of the concepts should provide, however completely
512 499
  without implementations and real data structures behind the
513 500
  interface. On the other hand they should provide nothing else. All
514 501
  the algorithms working on a data structure meeting a certain concept
515 502
  should compile with these classes. (Though it will not run properly,
516 503
  of course.) In this way it is easily to check if an algorithm
517 504
  doesn't use any extra feature of a certain implementation.
518 505

	
519 506
- The concept descriptor classes also provide a <em>checker class</em>
520 507
  that makes it possible to check whether a certain implementation of a
521 508
  concept indeed provides all the required features.
522 509

	
523 510
- Finally, They can serve as a skeleton of a new implementation of a concept.

26 26
The \e LGF is a <em>column oriented</em>
27 27
file format for storing graphs and associated data like
28 28
node and edge maps.
29 29

	
30 30
Each line with \c '#' first non-whitespace
31 31
character is considered as a comment line.
32 32

	
33 33
Otherwise the file consists of sections starting with
34 34
a header line. The header lines starts with an \c '@' character followed by the
35 35
type of section. The standard section types are \c \@nodes, \c
36 36
\@arcs and \c \@edges
37 37
and \@attributes. Each header line may also have an optional
38 38
\e name, which can be use to distinguish the sections of the same
39 39
type.
40 40

	
41 41
The standard sections are column oriented, each line consists of
42 42
<em>token</em>s separated by whitespaces. A token can be \e plain or
43 43
\e quoted. A plain token is just a sequence of non-whitespace characters,
44 44
while a quoted token is a
45 45
character sequence surrounded by double quotes, and it can also
46 46
contain whitespaces and escape sequences.
47 47

	
48 48
The \c \@nodes section describes a set of nodes and associated
49 49
maps. The first is a header line, its columns are the names of the
50 50
maps appearing in the following lines.
51 51
One of the maps must be called \c
52 52
"label", which plays special role in the file.
53 53
The following
54 54
non-empty lines until the next section describes nodes of the
55 55
graph. Each line contains the values of the node maps
56 56
associated to the current node.
57 57

	
58 58
\code

63 63
 3      (40,10)      10      "Third node"
64 64
\endcode
65 65

	
66 66
The \c \@arcs section is very similar to the \c \@nodes section,
67 67
it again starts with a header line describing the names of the maps,
68 68
but the \c "label" map is not obligatory here. The following lines
69 69
describe the arcs. The first two tokens of each line are
70 70
the source and the target node of the arc, respectively, then come the map
71 71
values. The source and target tokens must be node labels.

The \c \@edges is just a synonym of \c \@arcs. The @arcs section can
81
The \c \@edges is just a synonym of \c \@arcs. The \@arcs section can
82 82
also store the edge set of an undirected graph. In such case there is
83 83
a conventional method for store arc maps in the file, if two columns
84 84
has the same caption with \c '+' and \c '-' prefix, then these columns
85 85
can be regarded as the values of an arc map.
86 86

	
87 87
The \c \@attributes section contains key-value pairs, each line
88 88
consists of two tokens, an attribute name, and then an attribute
89 89
value. The value of the attribute could be also a label value of a
90 90
node or an edge, or even an edge label prefixed with \c '+' or \c '-',
91 91
which regards to the forward or backward directed arc of the
92 92
corresponding edge.

\page migration Migration from the 0.x Series
23 23

	
24 24
This guide gives an in depth description on what has changed compared
25 25
to the 0.x release series.
26 26

	
27 27
Many of these changes adjusted automatically by the
28 28
<tt>script/lemon-0.x-to-1.x.sh</tt> tool. Those requiring manual
29 29
update are typeset <b>boldface</b>.
30 30

	
31 31
\section migration-graph Graph Related Name Changes
32 32

	
33 33
- \ref concepts::Digraph "Directed graphs" are called \c Digraph and
34 34
  they have <tt>Arc</tt>s (instead of <tt>Edge</tt>s), while
35 35
  \ref concepts::Graph "undirected graphs" are called \c Graph
36 36
  (instead of \c UGraph) and they have <tt>Edge</tt>s (instead of
37 37
  <tt>UEdge</tt>s). These changes reflected thoroughly everywhere in
38 38
  the library. Namely,
39 39
  - \c Graph -> \c Digraph
40 40
    - \c %ListGraph -> \c ListDigraph, \c %SmartGraph -> \c SmartDigraph etc.
41 41
  - \c UGraph -> \c Graph
42 42
    - \c ListUGraph -> \c ListGraph, \c SmartUGraph -> \c SmartGraph etc.
43 43
  - \c Edge -> \c Arc, \c UEdge -> \c Edge
44 44
  - \c EdgeMap -> \c ArcMap, \c UEdgeMap -> \c EdgeMap
45 45
  - \c EdgeIt -> \c ArcIt, \c UEdgeIt -> \c EdgeIt
46 46
  - Class names and function names containing the words \c graph,
47 47
    \c ugraph, \e edge or \e arc should also be updated.
48 48
- <b>The two endpoints of an (\e undirected) \c Edge can be obtained by the
49 49
  <tt>u()</tt> and <tt>v()</tt> member function of the graph
50 50
  (instead of <tt>source()</tt> and <tt>target()</tt>). This change
51 51
  must be done by hand.</b>
52 52
  \n Of course, you can still use <tt>source()</tt> and <tt>target()</tt>
53 53
  for <tt>Arc</tt>s (directed edges).
54 54

	
55 55
\warning
56 56
<b>The <tt>script/lemon-0.x-to-1.x.sh</tt> tool replaces all instances of
57 57
the words \c graph, \c digraph, \c edge and \c arc, so it replaces them
58 58
in strings, comments etc. as well as in all identifiers.</b>
59 59

\section migration-lgf LGF tools 
60
\section migration-lgf LGF tools
61 61
 - The \ref lgf-format "LGF file format" has changed,
62 62
   <tt>\@nodeset</tt> has changed to <tt>\@nodes</tt>,
63 63
   <tt>\@edgeset</tt> and <tt>\@uedgeset</tt> to <tt>\@arcs</tt> or
64 64
   <tt>\@edges</tt>, which become completely equivalents. The
65 65
   <tt>\@nodes</tt>, <tt>\@edges</tt> and <tt>\@uedges</tt> sections are
66 66
   removed from the format, the content of them should be
67 67
   the part of <tt>\@attributes</tt> section. The data fields in
68 68
   the sections must follow a strict format, they must be either character
69 69
   sequences without whitespaces or quoted strings.
70 70
 - The <tt>LemonReader</tt> and <tt>LemonWriter</tt> core interfaces
71 71
   are no longer available.
72 72
 - The implementation of the general section readers and writers has changed
73 73
   they are simple functors now. Beside the old
74 74
   stream based section handling, currently line oriented section
75 75
   reading and writing are also supported. In the
76 76
   section readers the lines must be counted manually. The sections
77 77
   should be read and written with the SectionWriter and SectionReader
78 78
   classes.
79 79
 - Instead of the item readers and writers, item converters should be
80 80
   used. The converters are functors, which map the type to
81 81
   std::string or std::string to the type. The converters for standard
82 82
   containers hasn't yet been implemented in the new LEMON. The converters
83 83
   can return strings in any format, because if it is necessary, the LGF
84 84
   writer and reader will quote and unquote the given value.
85 85
 - The DigraphReader and DigraphWriter can used similarly to the
86 86
   0.x series, however the <tt>read</tt> or <tt>write</tt> prefix of
87 87
   the member functions are removed.
88 88
 - The new LEMON supports the function like interface, the \c
89 89
   digraphReader and \c digraphWriter functions are more convenient than
90 90
   using the classes directly.
91 91

	
92 92
\section migration-search BFS, DFS and Dijkstra
93 93
- <b>Using the function interface of BFS, DFS and %Dijkstra both source and
94 94
  target nodes can be given as parameters of the <tt>run()</tt> function
95 95
  (instead of \c bfs(), \c dfs() or \c dijkstra() itself).</b>
96 96
- \ref named-templ-param "Named class template parameters" of \c Bfs,
97 97
  \c Dfs, \c Dijkstra, \c BfsVisit, \c DfsVisit are renamed to start
98 98
  with "Set" instead of "Def". Namely,
99 99
  - \c DefPredMap -> \c SetPredMap
100 100
  - \c DefDistMap -> \c SetDistMap
101 101
  - \c DefReachedMap -> \c SetReachedMap
102 102
  - \c DefProcessedMap -> \c SetProcessedMap
103 103
  - \c DefHeap -> \c SetHeap
104 104
  - \c DefStandardHeap -> \c SetStandardHeap
105 105
  - \c DefOperationTraits -> \c SetOperationTraits
106 106
  - \c DefProcessedMapToBeDefaultMap -> \c SetStandardProcessedMap
107 107

	
108 108
\section migration-error Exceptions and Debug tools
109 109

	
110 110
<b>The class hierarchy of exceptions has largely been simplified. Now,
111 111
only the i/o related tools may throw exceptions. All other exceptions
112 112
have been replaced with either the \c LEMON_ASSERT or the \c LEMON_DEBUG
113 113
macros.</b>
114 114

	
115 115
<b>On the other hand, the parameter order of constructors of the
116 116
exceptions has been changed. See \ref IoError and \ref FormatError for
117 117
more details.</b>
118 118

	
119 119
\section migration-other Others
120 120
- <b>The contents of <tt>graph_utils.h</tt> are moved to <tt>core.h</tt>
121 121
  and <tt>maps.h</tt>. <tt>core.h</tt> is included by all graph types,
122 122
  therefore it usually do not have to be included directly.</b>
123 123
- <b><tt>path_utils.h</tt> is merged to \c path.h.</b>
124 124
- <b>The semantic of the assignment operations and copy constructors of maps
125 125
  are still under discussion. So, you must copy them by hand (i.e. copy
126 126
  each entry one-by-one)</b>
127 127
- <b>The parameters of the graph copying tools (i.e. \c GraphCopy,
128 128
  \c DigraphCopy) have to be given in the from-to order.</b>
129 129
- \c copyDigraph() and \c copyGraph() are renamed to \c digraphCopy()
130 130
  and \c graphCopy(), respectively.
131 131
- <b>The interface of \ref DynArcLookUp has changed. It is now the same as
132 132
  of \ref ArcLookUp and \ref AllArcLookUp</b>
133 133
- Some map types should also been renamed. Namely,
134 134
  - \c IntegerMap -> \c RangeMap
135 135
  - \c StdMap -> \c SparseMap
136 136
  - \c FunctorMap -> \c FunctorToMap
137 137
  - \c MapFunctor -> \c MapToFunctor
138 138
  - \c ForkWriteMap -> \c ForkMap
139 139
  - \c StoreBoolMap -> \c LoggerBoolMap
140 140
- \c dim2::BoundingBox -> \c dim2::Box
141 141
