‘Biomolecular Motor-based’ Computer Promises Speed and Reduced Power

Mar 2, 2016 |

Combinatorial tasks are among the hardest for traditional computers. A good example is finding the optimum path through a large complicated network. Every possible path must be evaluated and as datasets grow the computing time grows exponentially making some tasks unfeasible. One practical example is verification of VLSI (very large scale integrated) semiconductor circuit design. Read more…
