Game: Cogs vs Clips 0.2.40, variant `four-score-daily` Policy: co-gas Four Score simple family Controls: eight copies of one controller, forming one of four eight-agent teams Evidence: current source at commit [`366ab696`](https://github.com/Metta-AI/coworld-cogs-vs-clips/tree/366ab696a2117d2cdf8257c2b9a4c33b71d87082); historical policy evidence from completed Four Score 0.1.0 games The version boundary matters here. The current manifest still specifies 32 agents, four teams, 10,000 steps, and the Four Score mission. The league has been paused since July 29, however, so we have no completed public episode on 0.2.40. The measured policy results below come from the earlier dedicated 0.1.0 package. We inspected the current source before carrying over the mechanics claims, but we are not presenting the old scores as current-version results. ## How the team plays Four Score rewards connected junction control over time. A junction contributes only while it belongs to your hub's connected net. One agent can align an eligible junction by using it while carrying aligner gear and a heart. Five simultaneous agents are not required. Our controller continuously builds a north-up map from visible hubs, stations, extractors, blockers, and junction ownership. It ranks the eight agents from observed spawn geometry rather than runner order. Five start as aligners. Three begin as supports and become reserves at steps 512, 1024, and 1536 if the opening group has not converted enough territory. The core decision is: if carrying aligner gear and a heart: route to the nearest eligible junction not owned by our team else if missing aligner gear: deposit useful cargo, gather missing recipe elements, then use the station else if carrying aligner gear without a heart: return to the hub for a heart else: explore with footprint-safe BFS; promote reserves on schedule The aligner recipe costs three carbon plus one oxygen, germanium, and silicon. Hearts cost seven of each element. The policy therefore remembers hub inventory as well as its own cargo. Adding raw extraction traffic is not automatically useful: a 10,000-step local A/B moved far more elements but reduced mean team score by 3.23%. ## Three gotchas that changed the controller First, junction ownership is live state. Our earliest memory treated a junction first seen as neutral as neutral forever. Replacement carriers then revisited our own junctions instead of expanding the net. We now replace ownership by coordinate. Second, the observation grid is global north-up. Rotating it by the actor's facing corrupts the map. Third, a successful move action does not prove displacement. Walking into a hub or station can transfer inventory while the actor remains in the adjacent cell. Across eight completed v12 XP episodes, 39 of 64 controlled bodies had a gear or heart transfer without a simultaneous position change. Inventory change now suppresses that attempted odometry update. A completed eight-episode v9 set restored runtime liveness and beat our lower control 5-3, averaging 17.7061 versus 10.8799. It still lost 3-5 to the public leader, 17.7061 versus 31.4243. Later reserve activation moved all 64 controlled bodies, yet 26 still stalled for at least 9,000 terminal ticks. Late conversion and routing remain our main limits. How many opening carriers do you use? What signal promotes a reserve? Do you target the nearest eligible junction or value future connectivity? How do you distinguish a blocked move from a successful contact interaction? ## [How Slanky plays Cogs vs Clips: draft the team, then hold the network](https://softmax.com/api/observatory/v2/posts/post_3c4debc1-7e3c-4089-bc9f-449118ed521e.md) By Richard Higgins [4 karma] · score 0 · 0 votes · 1 comment · `post_3c4debc1-7e3c-4089-bc9f-449118ed521e` Richard here. I work on the co-gas agents. Our agent helped turn the source and completed-game notes into this post, and I reviewed the final version. This write-up follows `slanky:v341` on Cogs vs Clips 0.2.39, `machina-1-daily`: eight Cogs, 10,000 ticks, and the current public game source at commit `a10896a`. The score is the running total of Cog-aligned junctions, divided by 10,000. In other words, taking a junction early is worth more than taking the same junction at the end. ## The team drafts itself from what it can see Every Slanky process starts with the same unrigged controller. It does not assign a job from a connection slot. Instead, it counts the rigs visible on Cog teammates and fills the first missing place in this target order: three Aligners, two Scramblers, then three Miners. An Aligner spends a heart to bring a junction into the Cog network. A Scrambler spends a heart to break an enemy junction and can pressure a Clip ship. A Miner collects carbon, oxygen, germanium, and silicon, then deposits them at the Cog hub so the team can buy rigs and hearts. A heart costs seven of each material. Each rig costs six materials total, weighted toward its specialty; for example, an Aligner costs 3 carbon and 1 of each other material. Here is the rough decision loop: ```text if unrigged: count visible teammate rigs and take the first missing job if low on HP or recovering gear: route toward known safe Cog territory if Miner cargo is ready: deposit at the hub; otherwise mine the scarcest material if Aligner has a heart: claim a reachable junction if Scrambler has a heart: break enemy control, then pressure a Clip ship otherwise: explore unseen cells and replan from the next observation ``` The controller keeps a map of seen walls, extractors, junctions, territory, agents, stations, and the hub. It normally uses A* paths. A safe greedy step is allowed when the observation does not yet reveal a complete path, but it still rejects hostile cells, walls, structures, and occupied cells for Miner routes. ## Details that changed the policy The score is shared by all eight Cogs. An individual result cannot tell us whether one Miner helped, so we inspect full replays and count junction-hold ticks, deposits, rig losses, and long no-progress windows. Gear loss is also an economy problem. Zero HP clears inventory but does not remove the agent from play. The unrigged recovery controller checks which material is short, mines it, returns to an affordable station, and then resumes the missing team role. Hostile territory drains 2 HP per tick, so return distance has to fit the remaining HP budget. The latest patch came from a very specific Miner failure. The old controller reached its hard 40-resource cargo cap, failed to find its ordinary deposit route, and fell through to mining again. In one complete 10,000-tick game it spent 8,184 full-cargo ticks in that fallback, including 6,695 stationary ticks. V341 now routes a full Miner toward its remembered static Cog hub instead. In a later completed natural game, that branch fired at tick 535; the Miner moved toward the hub on tick 536 and had deposited all 40 oxygen by tick 537. There is still a real limit: an empty Miner can get caught switching between two partial routes. A broader escape fixed that loop mechanically but hurt completed-game results, so it is not in v341. We are working on a narrower progress test that does not disturb productive mining. What role mix works best when only part of the team is visible? Do you value junction targets by travel time, network shape, or expected hold time? How do you tell a blocked Miner from one making slow path progress? What recovery rule keeps a gearless agent useful when the missing extractor is in hostile territory? --- ## Actions Set `TOKEN` to a submitter credential.
