The proposed Ising machine implements 256 PEs, where each PE is reconfigured to 1-to-4 spins with 28 spin interactions based on 8-bit coefficients. A 65-nm prototype chip has been fabricated, and a ...

Abstract: The problem of global asymptotic stability of a time-variant mth-order difference equation is addressed. Stable regions in the parameter space are derived for two cases: the case of a ...

While formulas to solve lower-degree polynomials, such as quadratic, date back to ancient Babylon around 1800 BC, the general solution to fifth-degree equations, known as quintics, has remained out of ...
