Some of my larger annealer embeddings (~200 qubits) don't anneal down to the ground state while some of them do very easily.
Are there established guidelines for designing annealer embeddings to ensure that ground state configurations can be easily found? If so, where can this information be found?
If not, is addressing this issue more a matter of properly setting annealer parameters/annealing schedule. What are some good papers with information on this?
