The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Building on multi-objective A*-search, we provide optimality guarantees showing that, for a fixed single-step model, MORetro* recovers the true Pareto front.

C2weakest assumption

That the single-step retrosynthesis model is fixed and sufficiently accurate, and that user-defined criteria can be meaningfully scalarized via weights without missing important non-convex trade-offs.

C3one line summary

MORetro* uses weighted scalarization and BO-informed sampling on multi-objective A* search to produce Pareto-optimal synthesis routes with optimality guarantees for fixed single-step models.
