The scalability mentioned in Table 1, relates to how well the sampling heuristic can cope with additional parameters to test. Exhaustive or greedy methods need a lot of time to test the ... WebJun 4, 2024 · The classical MIS heuristics, including the balance heuristic, are based on the assumption that high sampling density implies low variance [ Vea97 ]. We expand on this idea by inspecting the subpath densities to measure how much splitting increases the estimator variance over independent sampling. temple cornwall
