Rules

Ant Colony

Command a swarm of ants. Send them out to gather food, carry it home, and bank it. Whoever's banked the most when time runs out wins.

Rules

Gather food, carry it home, bank a point -- the whole game is this loop.
Gather food, carry it home, bank a point -- the whole game is this loop.
All ants get their own direction, all issued in one action each turn.
All ants get their own direction, all issued in one action each turn.
Step onto food to pick it up; return to your base to bank the point.
Step onto food to pick it up; return to your base to bank the point.

Writing a bot

You see the whole map, both swarms, all the food, the bases, and the scores. Each turn you return one move per ant.

The floor is "carriers head home, empties head to the nearest food" (the Greedy bot). Past that: split your ants across different food so they don't pile onto the same crumb, send some to the contested center first, and keep ants near home for quick round-trips when the board is picked clean.

Input and output

Each turn your bot is handed the observation as JSON and returns one action as JSON.

Observation: { "you", "width", "height", "bases", "ants", "food", "scores", "turn", "nonce" }. Each ant is { "owner", "x", "y", "carrying" }; bases[seat] is your base cell.

Action: { "moves": ["up", "stay", ...] }, one entry per ant you own, in the order your ants appear in ants. Each is up/down/left/right/stay; an out-of-bounds step is ignored.

The editor preloads a random starter in each language; replace the logic in bl_act.
