A new algorithm for DNA based computation

A common feature of DNA computing involves the use of molecular biology techniques to extract molecules representing the solution to a computation from a reaction mixture. Current applied extraction methods often employ PCR (polymerase chain reactions) and/or gel electrophoresis, both of which we believe are too time-consuming and error-prone to yield a practical DNA-based molecular computing capability. This paper suggests a new approach to solving the Hamiltonian graph and similar combinatorial problems that avoids these traditional techniques in favor of a purely enzymatic methodology
