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

The strategy is shown to generate sublinear regret in the source-seeking task, while simulations demonstrate its effectiveness in localising radioactive sources.

C2weakest assumption

That the radiation intensity field can be adequately modeled by a heteroscedastic Gaussian process whose noise structure remains stable enough for the regret bound to hold in realistic environments.

C3one line summary

A Bayesian optimization method with heteroscedastic Gaussian process surrogate and movement switching cost achieves sublinear regret and effective source localization in simulations for radioactive source seeking.
