 required

run 

run(
    time_limit_seconds: int = 5,
    max_failed_analyses: int = 10,
) -> Sequence[Analysis]

Parameters:

Name Type Description Default
time_limit_seconds int

Wall-clock seconds allowed for the full chain before early exit.

 5
max_failed_analyses int

Maximum number of failing analyses to collect before stopping; also the max returned.
