常用示例
Compute shortest path from a source node in a graph
dijkstra -p [source_node] [input.dot]
Output distance matrix for all pairs of nodes
dijkstra -d [input.dot]
Write processed graph to output file
dijkstra [input.dot] -o [output.dot]
Compute shortest paths and output to file
dijkstra -p [source_node] -o [output.dot] [input.dot]
说明
dijkstra is a specialized Graphviz filter implementing Dijkstra's shortest path algorithm for graph analysis. It reads graph descriptions in DOT format, computes shortest paths between nodes, and outputs modified graphs with calculated distances or path information. The tool can calculate distance matrices showing the shortest path length between all pairs of nodes in a graph. It modifies graph attributes to reflect path calculations, which can then be used by other Graphviz layout tools for visualization. This utility is part of the Graphviz suite and is primarily used for network analysis, routing problems, and graph algorithm research. It processes graphs with weighted edges and can output results in various formats compatible with other Graphviz tools.
参数
- -o _file_
- Output file.
- -p _node_
- Set source node for shortest path computation.
- -d
- Output distance matrix.

How do I run a basic dijkstra example?
Run `dijkstra -p [source_node] [input.dot]` in a terminal, then adjust file names, paths, flags, or remote targets for your system.
What does -o _file_ do in dijkstra?
Output file.
