Confirmation
Options for the optional confirmation stage run after all members of a concurrent solver run complete. Members can return "best" solutions estimated with different precision (different replication counts, different luck), so picking the winner from point estimates alone favors noise. The confirmation stage re-evaluates the top candidates with common random numbers and picks the winner from the confirmed estimates — standard ranking-and-selection hygiene.
Parameters
top
the number of best candidate solutions to confirm; must be at least 1
replications
the number of replications for each confirmed candidate; must be at least 1
