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 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 toward solving the Hamiltonian Graph and similar combinatorial problems that avoids these traditional techniques in favor of a purely enzymatic methodology
