qiskit.dagcircuit.DAGCircuit.collect_runs

DAGCircuit.collect_runs(namelist)

Return a set of non-conditional runs of 《op》 nodes with the given names.

For example, 《… h q[0]; cx q[0],q[1]; cx q[0],q[1]; h q[1]; ..》 would produce the tuple of cx nodes as an element of the set returned from a call to collect_runs([《cx》]). If instead the cx nodes were 《cx q[0],q[1]; cx q[1],q[0];》, the method would still return the pair in a tuple. The namelist can contain names that are not in the circuit’s basis.

Nodes must have only one successor to continue the run.
