"carry out complex computations extremely quickly—possibly, even faster than today's supercomputers and at vastly less cost than any existing quantum computers. The principle uses time delay to overcome the barriers in optimization problems (choosing the best option from a large number of possibilities)...  would not require complex decision-making and complicated computer code... potentially be implemented without a digital computer based on the physical principles of analog devices"
