💖 HAMHEURISTIC 💖

okay bestie, gather round, because this is the manual page for hamheuristic version 2.9.3 and it's literally the little tool that tries to sniff out hamiltonian cycles for you 🦋

✨ NAME ✨

hamheuristic — the manual page for hamheuristic 2.9.3, no cap 💅

---

🌸 SYNOPSIS 🌸

hamheuristic [-sgu] [-vq] [-V] [-L#] [-t#] [infile [outfile]]

---

👑 DESCRIPTION 👑

So here's the vibe: you point it at some graphs, and it applies a heuristic for finding hamiltonian cycles. It's giving "I'll do my best, no promises" energy 🧚

By default it outputs the ones it couldn't solve — yes, the unsuccessful ones, the flops, the "it's not you it's me" graphs. Periodt. 💀

• -s — force the output to be in sparse6 format ✨
• -g — force the output to be in graph6 format. And heads up: if you don't hand it -s or -g, the output format gets decided by the header — or, if there's no header at all, by the format of the first input graph. iykyk 🌈
• -V — plot twist era: write the ones where a cycle is found instead (or a path, if you're running with -p) 🙈
• -u — suppress output to outfile and give statistics instead 📊

little side note, bestie: the output file will have a header if and only if the input file does. That's an iff, so don't come for me 🫶

• -p — be content with a hamiltonian path, it doesn't have to be the full cycle, we're lowkey flexible 🌸
• -v — give a cycle or path if one is found. show me the receipts 👀
• -c — if a cycle or path is found, do an independent check of it. trust but verify, that's the motto 💅
• -L# — limit the number of sideways steps (default is 1000+40*n) 🚶♀️
• -t# — try it # times (default is 1). one and done, unless you say otherwise 💖
• -q — suppress auxiliary information. shhh 🤫

and that's the whole page, bestie!! every flag, every default, every iff, preserved, slayed, iconic. 💜

this was hamheuristic 2.9.3, from September 2026 — go forth and find those cycles, main character 🎀✨🦋
