Euler method versus RK45?

1 comment

In the code, the Euler method with fixed step length is implemented as the solver for the master equation. Why Runge Kutta method with 4th order accuracy and adjustable step...

SB Parameters fine-tuning

Currently, the parameters of the SB algorithm are hardcoded. Though they work quite well on unconstrained problems, we noticed a huge performance drop on constrained problems converted to QUBO/Ising formulations....
