高质量的DNA编码可以避免DNA分子间的非特异性杂交,提高DNA计算的有效性和可靠性。首先对DNA编码的约束条件进行归类,分析了各编码约束对编码质量的影响;然后研究了编码质量、编码数量、序列长度与DNA计算可靠性、有效性、可扩充性之间的关系;最后通过类比DNA编码问题和图的独立集问题,说明了求解最大DNA序列集合问题是NP完全的。
High quality DNA sequences can prevent the interference between different DNA molecules, and improve the reliability and effectiveness of DNA computation. At first, classified DNA constraints, and analyzed the influence of constraints on the quality of DNA sequences. Then the paper studied the relationship between DNA sequence and the efficiency of DNA computing. Finally, the paper carried on the analogy to DNA sequence design problem and graph independent set problem, and proved the maximum DNA sequences set problem was a NP complete problem.
