Deterministic computation on probability distributions is often a significantly more efficient alternative to Monte Carlo simulations and does not suffer from the challenges of convergence faced by Monte Carlo simulations. Signaloid's uncertainty-extended hardware (UxHw) technology is used for improving the speed and quality of computing tasks that are today solved using Monte Carlo simulations. Computing workloads involving Monte Carlo simulations are critical in industries including financial services (banking, insurance, capital markets), engineering (design, manufacturing, robotics, industrial automation), supply chain logistics, energy supply and energy trading.
