\page migration Migration from the 0.x Series |
|
23 |
|
|
24 |
This guide gives an in depth description on what has changed compared |
|
25 |
to the 0.x release series. |
|
26 |
|
|
27 |
Many of these changes adjusted automatically by the |
|
28 |
<tt>script/lemon-0.x-to-1.x.sh</tt> tool. Those requiring manual |
|
29 |
update are typeset <b>boldface</b>. |

\section migration-graph Graph Related Name Changes |
|
32 |
|
|
33 |
- \ref concepts::Digraph "Directed graphs" are called \c Digraph and |
|
34 |
they have <tt>Arc</tt>s (instead of <tt>Edge</tt>s), while |
|
35 |
\ref concepts::Graph "undirected graphs" are called \c Graph |
|
36 |
(instead of \c UGraph) and they have <tt>Edge</tt>s (instead of |
|
37 |
<tt>UEdge</tt>s). These changes reflected thoroughly everywhere in |
|
38 |
the library. Namely, |
|
39 |
- \c Graph -> \c Digraph |
|
40 |
- \c %ListGraph -> \c ListDigraph, \c %SmartGraph -> \c SmartDigraph etc. |
|
41 |
- \c UGraph -> \c Graph |
|
42 |
- \c ListUGraph -> \c ListGraph, \c SmartUGraph -> \c SmartGraph etc. |
|
43 |
- \c Edge -> \c Arc, \c UEdge -> \c Edge |
|
44 |
- \c EdgeMap -> \c ArcMap, \c UEdgeMap -> \c EdgeMap |
|
45 |
- \c EdgeIt -> \c ArcIt, \c UEdgeIt -> \c EdgeIt |
|
46 |
- Class names and function names containing the words \c graph, |
|
47 |
\c ugraph, \e edge or \e arc should also be updated. |
|
48 |
- <b>The two endpoints of an (\e undirected) \c Edge can be obtained by the |
|
49 |
<tt>u()</tt> and <tt>v()</tt> member function of the graph |
|
50 |
(instead of <tt>source()</tt> and <tt>target()</tt>). This change |
|
51 |
must be done by hand.</b> |
|
52 |
\n Of course, you can still use <tt>source()</tt> and <tt>target()</tt> |
|
53 |
for <tt>Arc</tt>s (directed edges). |
|
54 |
|
|
55 |
\warning |
|
56 |
<b>The <tt>script/lemon-0.x-to-1.x.sh</tt> tool replaces all instances of |
|
57 |
the words \c graph, \c digraph, \c edge and \c arc, so it replaces them |
|
58 |
in strings, comments etc. as well as in all identifiers.</b> |
|
59 |
|
|
60 |
\section migration-lgf LGF tools |
|
61 |
- The \ref lgf-format "LGF file format" has changed, |
|
62 |
<tt>\@nodeset</tt> has changed to <tt>\@nodes</tt>, |
|
63 |
<tt>\@edgeset</tt> and <tt>\@uedgeset</tt> to <tt>\@arcs</tt> or |
|
64 |
<tt>\@edges</tt>, which become completely equivalents. The |
|
65 |
<tt>\@nodes</tt>, <tt>\@edges</tt> and <tt>\@uedges</tt> sections are |
|
66 |
removed from the format, the content of them should be |
|
67 |
the part of <tt>\@attributes</tt> section. The data fields in |
|
68 |
the sections must follow a strict format, they must be either character |
|
69 |
sequences without whitespaces or quoted strings. |
|
70 |
- The <tt>LemonReader</tt> and <tt>LemonWriter</tt> core interfaces |
|
71 |
are no longer available. |
|
72 |
- The implementation of the general section readers and writers has changed |
|
73 |
they are simple functors now. Beside the old |
|
74 |
stream based section handling, currently line oriented section |
|
75 |
reading and writing are also supported. In the |
|
76 |
section readers the lines must be counted manually. The sections |
|
77 |
should be read and written with the SectionWriter and SectionReader |
|
78 |
classes. |
|
79 |
- Instead of the item readers and writers, item converters should be |
|
80 |
used. The converters are functors, which map the type to |
|
81 |
std::string or std::string to the type. The converters for standard |
|
82 |
containers hasn't yet been implemented in the new LEMON. The converters |
|
83 |
can return strings in any format, because if it is necessary, the LGF |
|
84 |
writer and reader will quote and unquote the given value. |
|
85 |
- The DigraphReader and DigraphWriter can used similarly to the |
|
86 |
0.x series, however the <tt>read</tt> or <tt>write</tt> prefix of |
|
87 |
the member functions are removed. |
|
88 |
- The new LEMON supports the function like interface, the \c |
|
89 |
digraphReader and \c digraphWriter functions are more convenient than |
|
90 |
using the classes directly. |
|
91 |
|
|
92 |
\section migration-search BFS, DFS and Dijkstra |
|
93 |
- <b>Using the function interface of BFS, DFS and %Dijkstra both source and |
|
94 |
target nodes can be given as parameters of the <tt>run()</tt> function |
|
95 |
(instead of \c bfs(), \c dfs() or \c dijkstra() itself).</b> |
|
96 |
- \ref named-templ-param "Named class template parameters" of \c Bfs, |
|
97 |
\c Dfs, \c Dijkstra, \c BfsVisit, \c DfsVisit are renamed to start |
|
98 |
with "Set" instead of "Def". Namely, |
|
99 |
- \c DefPredMap -> \c SetPredMap |
|
100 |
- \c DefDistMap -> \c SetDistMap |
|
101 |
- \c DefReachedMap -> \c SetReachedMap |
|
102 |
- \c DefProcessedMap -> \c SetProcessedMap |
|
103 |
- \c DefHeap -> \c SetHeap |
|
104 |
- \c DefStandardHeap -> \c SetStandardHeap |
|
105 |
- \c DefOperationTraits -> \c SetOperationTraits |
|
106 |
- \c DefProcessedMapToBeDefaultMap -> \c SetStandardProcessedMap |
|
107 |
|
|
108 |
\section migration-error Exceptions and Debug tools |
|
109 |
|
|
110 |
<b>The class hierarchy of exceptions has largely been simplified. Now, |
|
111 |
only the i/o related tools may throw exceptions. All other exceptions |
|
112 |
have been replaced with either the \c LEMON_ASSERT or the \c LEMON_DEBUG |
|
113 |
macros.</b> |
|
114 |
|
|
115 |
<b>On the other hand, the parameter order of constructors of the |
|
116 |
exceptions has been changed. See \ref IoError and \ref FormatError for |
|
117 |
more details.</b> |
|
118 |
|
|
119 |
\section migration-other Others |
|
120 |
- <b>The contents of <tt>graph_utils.h</tt> are moved to <tt>core.h</tt> |
|
121 |
and <tt>maps.h</tt>. <tt>core.h</tt> is included by all graph types, |
|
122 |
therefore it usually do not have to be included directly.</b> |
|
123 |
- <b><tt>path_utils.h</tt> is merged to \c path.h.</b> |
|
124 |
- <b>The semantic of the assignment operations and copy constructors of maps |
|
125 |
are still under discussion. So, you must copy them by hand (i.e. copy |
|
126 |
each entry one-by-one)</b> |
|
127 |
- <b>The parameters of the graph copying tools (i.e. \c GraphCopy, |
|
128 |
\c DigraphCopy) have to be given in the from-to order.</b> |
|
129 |
- \c copyDigraph() and \c copyGraph() are renamed to \c digraphCopy() |
|
130 |
and \c graphCopy(), respectively. |
|
131 |
- <b>The interface of \ref DynArcLookUp has changed. It is now the same as |
|
132 |
of \ref ArcLookUp and \ref AllArcLookUp</b> |
|
133 |
- Some map types should also been renamed. Namely, |
|
134 |
- \c IntegerMap -> \c RangeMap |
|
135 |
- \c StdMap -> \c SparseMap |
|
136 |
- \c FunctorMap -> \c FunctorToMap |
|
137 |
- \c MapFunctor -> \c MapToFunctor |
|
138 |
- \c ForkWriteMap -> \c ForkMap |
|
139 |
- \c StoreBoolMap -> \c LoggerBoolMap |
|
140 |
- \c dim2::BoundingBox -> \c dim2::Box |

LEMON is an open source library written in C++. It provides |
6 | 6 |
easy-to-use implementations of common data structures and algorithms |
7 | 7 |
in the area of optimization and helps implementing new ones. The main |
8 | 8 |
focus is on graphs and graph algorithms, thus it is especially |
9 | 9 |
suitable for solving design and optimization problems of |
10 | 10 |
telecommunication networks. To achieve wide usability its data |
11 | 11 |
structures and algorithms provide generic interfaces. |

\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 |
You are free to use the graph structure that fit your requirements |
44 | 44 |
the best, most graph algorithms and auxiliary data structures can be used |
45 |
with any graph |
|
45 |
with any graph structure. |

72 | 75 |
\brief Tools to create new maps from existing ones |
73 | 76 |
|
74 | 77 |
This group describes map adaptors that are used to create "implicit" |
75 | 78 |
maps from other maps. |
76 | 79 |
|
77 | 80 |
Most of them are \ref lemon::concepts::ReadMap "read-only maps". |
78 | 81 |
They can make arithmetic and logical operations between one or two maps |
79 | 82 |
(negation, shifting, addition, multiplication, logical 'and', 'or', |
80 | 83 |
'not' etc.) or e.g. convert a map to another one of different Value type. |
81 | 84 |
|
82 | 85 |
The typical usage of this classes is passing implicit maps to |
83 | 86 |
algorithms. If a function type algorithm is called then the function |
84 | 87 |
type map adaptors can be used comfortable. For example let's see the |
85 |
usage of map adaptors with the \c |
|
88 |
usage of map adaptors with the \c graphToEps() function. |
|
86 | 89 |
\code |
87 | 90 |
Color nodeColor(int deg) { |
88 | 91 |
if (deg >= 2) { |
89 | 92 |
return Color(0.5, 0.0, 0.5); |
90 | 93 |
} else if (deg == 1) { |
91 | 94 |
return Color(1.0, 0.5, 1.0); |
92 | 95 |
} else { |
93 | 96 |
return Color(0.0, 0.0, 0.0); |
94 | 97 |
} |
95 | 98 |
} |
96 | 99 |
|
97 | 100 |
Digraph::NodeMap<int> degree_map(graph); |
98 | 101 |
|
99 |
|
|
102 |
graphToEps(graph, "graph.eps") |
|
100 | 103 |
.coords(coords).scaleToA4().undirected() |
101 | 104 |
.nodeColors(composeMap(functorToMap(nodeColor), degree_map)) |
102 | 105 |
.run(); |
103 | 106 |
\endcode |
104 | 107 |
The \c functorToMap() function makes an \c int to \c Color map from the |
105 |
\ |
|
108 |
\c nodeColor() function. The \c composeMap() compose the \c degree_map |
|
106 | 109 |
and the previously created map. The composed map is a proper function to |
107 | 110 |
get the color of each node. |
108 | 111 |
|
109 | 112 |
The usage with class type algorithms is little bit harder. In this |
110 | 113 |
case the function type map adaptors can not be used, because the |
111 | 114 |
function map adaptors give back temporary objects. |
112 | 115 |
\code |
113 | 116 |
Digraph graph; |
114 | 117 |
|
115 | 118 |
typedef Digraph::ArcMap<double> DoubleArcMap; |
116 | 119 |
DoubleArcMap length(graph); |
117 | 120 |
DoubleArcMap speed(graph); |
118 | 121 |
|
119 | 122 |
typedef DivMap<DoubleArcMap, DoubleArcMap> TimeMap; |
120 | 123 |
TimeMap time(length, speed); |
121 | 124 |
|
122 | 125 |
Dijkstra<Digraph, TimeMap> dijkstra(graph, time); |
123 | 126 |
dijkstra.run(source, target); |
124 | 127 |
\endcode |
125 | 128 |
We have a length map and a maximum speed map on the arcs of a digraph. |
126 | 129 |
The minimum time to pass the arc can be calculated as the division of |
127 | 130 |
the two maps which can be done implicitly with the \c DivMap template |
128 | 131 |
class. We use the implicit minimum time map as the length map of the |
129 | 132 |
\c Dijkstra algorithm. |

266 | 268 |
|
267 | 269 |
This group describes the data/algorithm skeletons and concept checking |
268 | 270 |
classes implemented in LEMON. |
269 | 271 |
|
270 | 272 |
The purpose of the classes in this group is fourfold. |
271 | 273 |
|
272 | 274 |
- These classes contain the documentations of the concepts. In order |
273 | 275 |
to avoid document multiplications, an implementation of a concept |
274 | 276 |
simply refers to the corresponding concept class. |
275 | 277 |
|
276 | 278 |
- These classes declare every functions, <tt>typedef</tt>s etc. an |
277 | 279 |
implementation of the concepts should provide, however completely |
278 | 280 |
without implementations and real data structures behind the |
279 | 281 |
interface. On the other hand they should provide nothing else. All |
280 | 282 |
the algorithms working on a data structure meeting a certain concept |
281 | 283 |
should compile with these classes. (Though it will not run properly, |
282 | 284 |
of course.) In this way it is easily to check if an algorithm |
283 | 285 |
doesn't use any extra feature of a certain implementation. |
284 | 286 |
|
285 | 287 |
- The concept descriptor classes also provide a <em>checker class</em> |
286 | 288 |
that makes it possible to check whether a certain implementation of a |
287 | 289 |
concept indeed provides all the required features. |
288 | 290 |
|
289 | 291 |
- Finally, They can serve as a skeleton of a new implementation of a concept. |

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. |

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 |

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. |

The \c \@attributes section contains key-value pairs, each line |

consists of two tokens, an attribute name, and then an attribute |
