We are excited to share Sparse Ising Machines with p-bits are now out in Nature Electronics. Also check out the coverage by the College of Engineering.
Andrea and Navid's paper shows how invertible logic with p-bits can be useful to solve maximum satisfiability problems using sophisticated optimization algorithms such as parallel tempering.
Navid's paper "Computing with Invertible Logic: Combinatorial Optimization with Probabilistic Bits" has been accepted to the International Electron Devices Meeting (IEDM), 2021.
