Enum CollapseSchedule 

#[non_exhaustive]
pub enum CollapseSchedule {
    Serial,
    Ordered,
    Rounds,
    Adaptive,
}

The collapse the pipeline runs with RipsParams::collapse_edges set.

Every schedule gives the same diagram. Serial is the default and, in the registered studies, the fastest end to end on most inputs. Ordered gives the serial result, bit for bit, from a parallel run. Rounds gives a result that does not depend on the worker count and, on some inputs, a smaller reduced graph; its cost grows faster with the edge count than the serial cost. See collapse for the schedules and their certificates.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Serial

The serial schedule on one worker. It writes an algorithm version 1 certificate. The reduction still uses the whole thread budget.

Ordered

The ordered schedule on the run’s worker budget. It gives the same reduced graph and the same certificate as Serial.

Rounds

The rounds schedule on the run’s worker budget. It writes an algorithm version 2 certificate and gives the same result at every worker count, but not the serial result.

Adaptive

The adaptive version 3 schedule. It ranks currently valid removals by estimated downstream H1 or H2 work and can stop at a declared work limit. It runs serially; the reduction still uses the whole thread budget.
