PrxCa1-xMnO3 based Stochastic Neuron for Boltzmann Machine to Solve “Maximum Cut" Problem
Abstract

This invention presents an approach to solve complex computational problems, specifically focusing on the "Maximum Cut" problem. By leveraging a novel PrxCa1-xMnO3-based Stochastic Neuron for Boltzmann Machine (BM), the system introduces a new paradigm for tackling NP Hard problems, which have wide-ranging practical implications. The design incorporates analog and digital components to create a stochastic neuron capable of making probabilistic decisions, mimicking the behavior of neurons in the brain. By harnessing the stochastic switching properties of PCMO RRAM, the system achieves remarkable efficiency in solving NP Hard problems.
