Hello @willxujun, I believe that part of the problem might be that you're not using a chain strength parameter. In the sample_qubo statement, please add the parameter 'chain_strength=1500', and please...

Just to explain what I'm thinking, the EmbeddingComposite is doing an embedding for you, and as part of finding the embedding, it builds some "chains," in which qubits are constrained...

Hello @willxujun, my initial work shows that the chain_strength helps, but doesn't yet lead to a "correct solution." Could you share the expected answer that you're seeking?

One more question for you, @willxujun. What energy are you expecting? Do you have a calculation of it? (The "permutation matrix" is good, and it matches what I'm getting. I'd...

@willxujun, I get -7480 now, with different solvers, so we are indeed in the same range. No, you're not missing anything. This problem is a challenging one for the QPU....

Hello @willxujun, I have not forgotten this. I will come up with a strategy for you. It is taking longer than I'd hoped, but I will get there. Thanks for...

@willxujun, I apologize again, for the long delay - thanks for writing. I'm working on this today. I confirm that your second matrix does a little better - although it...

@willxujun, I started to research this today, and I am still looking for a set of steps for you to follow. One of our technical experts mentioned some techniques which...

Hello @yogesh078, sorry for the delay. can you provide information as to what is not working for you?

I had hoped it would be useful to have a contrast between the classic formulation and the DQM formulation - hence the "duplication".
