Generalized Probabilistic Approximate Optimization Algorithm - Nature Communications

|
By Shuvro Chowdhury, Flaviano Morone, Abdelrahman S. Abdelrahman
| Nature Verified
Abstract We introduce the generalized Probabilistic Approximate Optimization Algorithm (PAOA), a classical variational Monte Carlo framework that extends and formalizes the recently introduced PAOA, enabling parameterized and fast sampling on present-day Ising machines and probabilistic computers. PAOA operates by iteratively modifying the couplings of a network of binary stochastic units, guided by cost evaluations from independent samples.

Noise-augmented chaotic Ising machines for combinatorial optimization and sampling - Communications Physics

|
By Kyle Lee, Shuvro Chowdhury, Kerem Y. Camsari
| Nature Verified
Abstract Ising machines are hardware accelerators for combinatorial optimization and probabilistic sampling, using stochasticity to explore spin configurations and avoid local minima. We refine the previously proposed coupled chaotic bits (c-bits), which operate deterministically, by introducing noise. This improves performance in combinatorial optimization, achieving algorithmic scaling comparable to probabilistic bits (p-bits).
