Paper summary¶

Background and main changes¶

Four acting agents write JavaScript programs to control Mineflayer characters. An Observer summarizes world state, while chat and notes carry progress. The study concerns long-horizon coordination, programmatic tools, and persistent state, not a new training objective.

Core equation¶

The paper has no new parameter-optimization formula. The following notation summarizes the interaction without defining a new algorithm:

\[ a_t^{(i)}=\pi_i(o_{\le t}^{(i)},m_t),\qquad s_{t+1}=T(s_t,a_t^{(1:4)}). \]

Shared records do not replace feedback from the actual environment.

Offline and online results reported in the paper¶

The authors report one successful run in a random Easy-difficulty world, about 27 hours and 24,000 model calls. A single completion is not 100% success over multiple seeds and establishes no cost or reliability advantage over other systems.

No production online A/B is reported. This is a game-interaction case study, not an industrial traffic experiment.

Local reproduction¶

Only the reference, original figure, and cost review were completed. No commercial model was called and no game was run. The long interaction exceeds the single-card and local budget, so the full experiment was reviewed and not reproduced because of cost.

Reproduction limits¶

No local capability metrics, training results, or Evolve operator. No fabricated success receipt. See the batch acceptance contract.
