Probabilistic computing using probabilistic bits (p-bits) presents an efficient alternative to traditional CMOS logic for complex problem-solving, including simulated annealing and machine learning.
$$\begin{aligned} \sigma _i(t+1) = \textrm{sgn}\Bigl (r_i(t) + \textrm{tanh}\bigl (I_i(t+1)\bigr )\Bigr ), \end{aligned}$$ Simulated annealing that utilizes p-bits ...
