\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 |
|
57 |
with any graph structure. |

\brief Tools to create new maps from existing ones |
95 | 98 |
|
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 |
|
110 |
usage of map adaptors with the \c graphToEps() function. |
|
108 | 111 |
\code |
109 | 112 |
Color nodeColor(int deg) { |
110 | 113 |
if (deg >= 2) { |
111 | 114 |
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); |
116 | 119 |
} |
117 | 120 |
} |
118 | 121 |
|
119 | 122 |
Digraph::NodeMap<int> degree_map(graph); |
120 | 123 |
|
121 |
|
|
124 |
graphToEps(graph, "graph.eps") |
|
122 | 125 |
.coords(coords).scaleToA4().undirected() |
123 | 126 |
.nodeColors(composeMap(functorToMap(nodeColor), degree_map)) |
124 | 127 |
.run(); |
125 | 128 |
\endcode |
126 | 129 |
The \c functorToMap() function makes an \c int to \c Color map from the |
127 |
\ |
|
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 |
|
141 | 144 |
typedef DivMap<DoubleArcMap, DoubleArcMap> TimeMap; |
142 | 145 |
TimeMap time(length, speed); |
143 | 146 |
|
144 | 147 |
Dijkstra<Digraph, TimeMap> dijkstra(graph, time); |
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: |

|
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 |

The minimum cut problem is to find a non-empty and non-complete |
266 | 266 |
\f$X\f$ subset of the vertices with minimum overall capacity on |
267 | 267 |
outgoing arcs. Formally, there is \f$G=(V,A)\f$ directed graph, an |
268 | 268 |
\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: |

|
271 | 271 |
\f[ \min_{X \subset V, X\not\in \{\emptyset, V\}} |

This group contains algorithm objects and functions to calculate |

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. |

|
501 | 488 |
This group describes the data/algorithm skeletons and concept checking |
502 | 489 |
classes implemented in LEMON. |
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. |

\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 |
|
60 |
\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 |

<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 |

macros.</b> |
114 | 114 |

115 | 115 |
<b>On the other hand, the parameter order of constructors of the |
