2 Anchored Value Iteration

\ The accelerated rate of Anc-VI for the Bellman optimality operator is more technically challenging and is, in our view, the stronger contribution. However, we start by presenting the result for the Bellman consistency operator because it is commonly studied in the prior RL theory literature on accelerating value iteration [1, 31, 37, 38] and because the analysis in the Bellman consistency setup will serve as a good conceptual stepping stone towards the analysis in the Bellman optimality setup.
