Travelling Salesman

Describe the problem, answer any questions, and review the proposed changes. Applying settings leaves the form editable. Only Submit starts a run.

Your messages and progress stay on this page when you close and reopen LEGA. Sent messages and responses are saved in LEGA conversations. Unsent text is lost on refresh, so unfinished work triggers a warning. Saved submission drafts are separate from conversation history.

Each reply uses your earlier descriptions and clarifications, this problem type, and current form values. Files and unrelated account data are not sent. Preparation context is limited to 16,000 characters.
