def allow_early_termination(): Boolean

Determines whether a policy allows for canceling running tasks.
Determines whether a policy allows for canceling running tasks. If true, is_done will be called more often, increasing the required confidence level to terminate. Note that an early termination check is always conducted when timeouts occur regardless of this setting.

Returns a list of blacklisted worker_ids given a set of tasks, completed or not.
Returns a list of blacklisted worker_ids given a set of tasks, completed or not.
tasks
