cirq_google.line.placement.greedy.GreedySequenceSearch

Base class for greedy search heuristics.

cirq_google.line.placement.greedy.GreedySequenceSearch(
    device: 'cirq_google.GridDevice', start: GridQubit
) -> None

Specialized greedy heuristics should implement abstract _sequence_search method.

device Chip description.
start Starting qubit.

ValueError When start qubit is not part of a chip.

get_or_search() -> cirq_google.line.placement.anneal.LineSequence

Starts the search or gives previously calculated sequence.

Returns
The linear qubit sequence found.
