Goal seeking Quadratic Unconstrained Binary Optimization

open access: yesResults in Control and Optimization, 2022
The Quadratic Unconstrained Binary Optimization (QUBO) modeling and solution framework is a requirement for quantum and digital annealers. However optimality for QUBO problems of any practical size is extremely difficult to achieve.

Benchmark of quantum-inspired heuristic solvers for quadratic unconstrained binary optimization [PDF]

open access: yesScientific Reports, 2022
Recently, inspired by quantum annealing, many solvers specialized for unconstrained binary quadratic programming problems have been developed. For further improvement and application of these solvers, it is important to clarify the differences in their ...

Analyzing Quadratic Unconstrained Binary Optimization Problems via Multicommodity Flows [PDF]

open access: yesDiscrete Applied Mathematics, 2009
Quadratic Unconstrained Binary Optimization (QUBO) problems concern the minimization of quadratic polynomials in n {0, 1}-valued variables. These problems are NP-complete, but prior work has identified a sequence of polynomial-time computable lower bounds on the minimum value, denoted by C(2), C(3), C(4),….

Sampling electronic structure quadratic unconstrained binary optimization problems (QUBOs) with Ocean and Mukai solvers. [PDF]

open access: yesPLoS ONE, 2022
The most advanced D-Wave Advantage quantum annealer has 5000+ qubits, however, every qubit is connected to a small number of neighbors. As such, implementation of a fully-connected graph results in an order of magnitude reduction in qubit count.

Parallelizable search-space decomposition for large-scale combinatorial optimization problems using quadratic unconstrained binary optimization [PDF]

open access: yesScientific Reports
Combinatorial optimization problems are crucial in industry. However, many COPs are NP-hard, causing the search space to grow exponentially with problem size and rendering large-scale instances computationally intractable.

Quadratic unconstrained binary optimization and constraint programming approaches for lattice-based cyclic peptide docking [PDF]

open access: yesScientific Reports
The peptide-protein docking problem is an important problem in structural biology that facilitates rational and efficient drug design. In this work, we explore modeling and solving this problem with the quantum-amenable quadratic unconstrained binary ...

A smaller and more efficient one-hot encoding for QUBO [PDF]

open access: yesScientific Reports
One-hot constraints are widely used for quadratic unconstrained binary optimization (QUBO) in quantum and simulated annealing to solve optimization problems. They correspond to exactly-one constraints for Boolean satisfiability problems (SAT), which have

Q-LEAP: Millisecond Hyperdimensional Optimization for Full-Spectrum Optical Metamaterials. [PDF]

open access: yesAdv Sci (Weinh)
Q‐LEAP integrates physics‐informed residual machine learning with factorization‐machine‐encoded quantum annealing to design full‐spectrum optical metamaterials. It explores a 2108 design space and, in a single 2.56 ms annealing step, reaches 85.83% of the theoretical FoM limit, enabling selective 5‐8 µm emission with 3–5 and 8–14 µm suppression and ∼40×

Quadratic Unconstrained Binary Optimization Approach for Incorporating Solvency Capital into Portfolio Optimization

open access: yesRisks
In this paper, we consider the inclusion of the solvency capital requirement (SCR) into portfolio optimization by the use of a quadratic proxy model. The Solvency II directive requires insurance companies to calculate their SCR based on the complete loss
