Hybrid solvers for the Boolean Satisfiability problem: an exploration
… This thesis focuses on the design of feasible solvers for this problem. A SAT problem instance is a formula in propositional logic. A SAT solver attempts to find a solution for the formula. Our research focuses on a newer solver paradigm, hybrid solvers, where two solvers are combined in order …

Quantum-Powered Battery Scheduling in Modern Distribution Grids
… a constrained quadratic model (CQM) on D-Wave’s hybrid solver as well as a binary quadratic model (BQM), this thesis solves the optimal battery scheduling problem for a large number of batteries. To formulate the BQM, a quadratic unconstrained binary optimization (QUBO) format was chosen and in …
