DSB algorithm to solve the VRP problem

[sb12q]

Hello, I am using the DSB algorithm to solve the VRP problem and converting it into a Qubo matrix. SQA can achieve the expected effect, but using dSB cannot achieve the ideal effect. The matrix size is 150 * 150, and changing the coefficients such as time. step is useless. The result violates the constraint objective function and cannot achieve the ideal effect. I would like to ask how I can adjust it. Looking forward to your reply
