# Format

Files start with an arbitrary number of comment lines (lines starting with `#`), with two always existing:
- the line `# Nodes: <number of nodes>` (nodes are 0-indexed),
- and a line starting with `# thresholds` that contains a space-separated list of node thresholds.
After the comments follow an arbitrary amount of edge definitions of the form `<from> <to> <weight>`, one definition per line.
