class sequince.steps.mutation.adaptive.policies.base.MutationStepPolicy

Bases: Protocol

Choose mutation budgets using completed, iteration-level metrics.

Policies are called only at mutation-block boundaries. In particular, they never receive intermediate mutation states or metrics.

initialise(*, initial_steps, context)

Choose the budget for the first adaptive iteration.

Parameters:

• initial_steps (int)

• context (sequince.steps.context.StepContext)

Return type:

int

update(*, current_steps, metrics, context)

Choose the proposed budget for the next outer iteration.

Parameters:

• current_steps (int)

• metrics (sequince.steps.mutation.metrics.MutationMetricsOutput)

• context (sequince.steps.context.StepContext)

Return type:

int
