@abc.abstractmethod
place_circuit(
    circuit: cirq.AbstractCircuit,
    problem_topology: 'cirq.NamedTopology',
    shared_rt_info: 'cg.SharedRuntimeInfo',
    rs: np.random.RandomState
) -> Tuple['cirq.FrozenCircuit', Dict[Any, 'cirq.Qid']]

Place a circuit with a given topology.

Args
circuit The circuit.
problem_topology The topologies (i.e. connectivity) of the circuit.
shared_rt_info A cg.SharedRuntimeInfo object that may contain additional info to inform placement.
rs A RandomState to enable pseudo-random placement strategies.

Returns
A tuple of a new frozen circuit with the qubits placed and a mapping from input qubits or nodes to output qubits.
