This work introduces a novel combinatorial dimension of the reward class which is called the alignment dimension, and shows that it completely characterizes the alignment learnability --- a reward class is alignment learnable if and only if its alignment dimension is finite.

RD-MCTS, a Monte Carlo Tree Search framework that incorporates diagram-derived structural priors, constraint-consistent state transitions, and inference-time step-level process rewards is proposed, aimed at improving constraint-consistent reasoning on high-difficulty questions.
