Fast Parallel Solution for Set-Packing and Clique Problems by DNA-Based Computing

This paper shows how to use sticker to construct solution space of DNA for the library sequences in the set-packing problem and the clique problem. Then, with biological operations, we propose DNAbased algorithms to remove illegal solutions and to find legal solutions for the set-packing and clique problems from the solution space of sticker. Any NP-complete problem in Cook’s Theorem can be reduced and solved by the proposed DNA-based computing approach if its size is equal to or less than that of the set-packing problem. Otherwise, Cook’s Theorem is incorrect on DNA-based computing and a new DNA algorithm should be developed from the characteristics of the NP-complete problem. Finally, the result to DNA simulation is given. key words: biological computing, molecular computing, DNA-based computing
