If I try to transform a PUBO x\_0 x\_1 x\_2 to QUBO, certain documentation says that I need to add the constraint 6 x\_3 + 2 x\_0 x\_1 - 4 x\_0 x\_3 - 4 x\_1 x\_3 However, I need to arrive to a minima (there in this case 0) or…

I’m working with very large matrices for QUBO problems, and I’m currently using QBsolv from D-Wave. However, given that Qbsolv is being discontinued, I identified that D-wave has 2 solutions for this type of problem: Lea…
