The Applied Higher-Order Functions cataloguesrc/rainbow/algorithms/proofs/ahof/dec_pomdp_hs.clj1 definitions, 4 theorems

AHoF D83 Dec-POMDP Heuristic Search: search the space of joint policies with heuristic bounds; converged when the bound gap is within precision: converged? gap epsilon = decide (gap <= epsilon). Proved native and axiom-free (decision, two positive instances, at-most certificate, negative instance). Requires audit/decide-nnrat-at-most, nnrat/at-most, nnrat/decide-at-most-true-sound (all in the D63 checkpoint). Scope (measured by the kernel): this module has 4 worked instances (statements about specific values). None of its theorems is a guarantee about the algorithm for all inputs; `lein verify rainbow.algorithms.proofs.ahof.dec-pomdp-hs` prints this classification.
