Collection of Graph algorithms

Graph is implemented in adjacency matrix format, like:

SIZE
M A T
R I X
* * *

3
0 2 4
3 0 2
7 9 0

You can find example files in src/assets directory.

Collection list

For now there are 8 algorithms and some graph operations:

In graph.h you can:

• Load graph from adjacency matrix
• Export graph as adjacency matrix
• Export graph in DOT format

In graph_algorithms.h implemented:

• Depth First Search
• Bread First Search
• Dijkstra algorithm for finding shortest path.
• Floyd-Warshall algorithm for finding shortest path between all vertices.
• Prim algorithm for finding least spanning tree.

And there are 3 traveling salesman problem solving algorithms in src/graph/TSM directory:

• Ant Colony Optimization algorithm
• Genetic Algorithm
• Branches and Bounds algorithm

Console Interface

In addition, there are implemented console interface.

For building use:

make install

or

cmake . -B build && \
cmake --build build --target GraphApplication --config=Release

and launch:

./GraphApplication

Library

You can build a static library only.

For building only graph, use:

make graph.a

For build with algorithms, use:

make graph_algorithms.a

Or you can use cmake directly, see src/Makefile

Tests

There are some tests for these algorithms. You can build and run them to check everything is fine.

For building use:

make tests

or

cmake . -B build && \
cmake --build build --target GraphTests --config=Release

and launch:

./GraphTests

Note: Tests using src/assets files, make sure they are not edited.
