US Patent 7167847 - DNA Computer

DNA is a candidate material for molecular computation devices. This patent from Fujitsu uses a genetic algorithm approach to "evolve" a solution to a complex computational problem by breaking the problem down into smaller parts. Claim 1 reads:

1. A DNA computer for carrying out computations using DNAs, comprising: a dividing part configured to divide a problem that is to be solved into a plurality of partial problems; and an operation part configured to obtain a DNA sequence corresponding to a solution to the problem, by combining DNA sequences corresponding to solutions of the plurality of partial problems.
