Problem faced between SA and D-wave sampler solution
I have uploaded the image of QUBO matrix. But the solutions of dimod's simulated annealing sampler and D-wave sampler are not same. Simulated annealing sampler found the lower energy states but Dwave sampler gave something else (first 2 energy state are same). I have also checked the exact solver for all possible solutions.
the above image shows the QUBO matrix and Exact solution. where you can see first 3 states are lower energy states.
This above image shows the result of simulated annealing sampler and d-wave sampler. I think some embedding is required.
- But how to perform the embedding for this problem, if embedding can solve the issue?
- I found there are some issue with chain strength also. Is that a problem?
- How to fix this up?
