Stochastic (aka random-pulse) computer, uses time-wise random pulses, much alike those found in human brain. In the past decade it has been shown that it can be efficiently implemented in digital hardware, using only a few gates per mathematical operation, allowing for more functionality to be packed in a limited supply of hardware. It also possesses a high immunity to hardware failure and noise, much higher than digital and quantum computers in general. Finally, it operates without a clock: all computations are data driven, so at any moment it produces an optimum output given the input data.
