cirq_google.line.AnnealSequenceSearchStrategy

Linearized sequence search using simulated annealing method.

Inherits From: LinePlacementStrategy

cirq_google.line.AnnealSequenceSearchStrategy(
    trace_func: (Callable[[list[LineSequence], float, float, float, bool], None] | None) = None,
    seed: (int | None) = None
) -> None

efficiency improvements. Github issue: https://github.com/quantumlib/Cirq/issues/2217

trace_func Optional callable which will be called for each simulated annealing step with arguments: solution candidate (list of linear sequences on the chip), current temperature (float), candidate cost (float), probability of accepting candidate (float), and acceptance decision (boolean).
seed Optional seed value for random number generator.
