This paper proposes a DNA algorithm based on biological technology for the maximal matching problem. Maximum matching problem is a typical combinatorial optimization problem. The main idea of the algorithm is draw the line graph to observe adjacent edges firstly, then use the direct proportional length-based DNA strands to encode the given weighted graph edges. All data pool generated in a test tube...
Sticker model is one of the main DNA computing models, whose features are that it does not require extension of DNA strands in the biological process, does not require biological enzyme action and also the DNA strands can be reused In this paper, we try to solve the general 0-1 programming problem by utilizing these features of the model and its four basic operations (merger, separation, setting and...
After Adlemanpsilas paper published in 1994, a few of scholars solved some noted NP-complete problems on DNA computing. And all these methods of DNA computing are based on conventional Watson-Crick hydrogen bond of double helical DNA molecule. Here we show that triple stranded DNA structure mediated by RecA protein can be used for solving working operation problem. During the computation,sequence...
