Abstract:

The classical algorithms for k-edge induced sub-graphs of the directed graph are very inefficient due to their high complexity. To solve this problem, a DNA sticker algorithm for constructing sub-graphs is put forward in this paper. First, the basic constructs in the algorithm consist of some pre-defined sticker operations. And then, the algorithm is organized in some logical orders of basic constructs. The complexity analysis indicates that the new algorithm can construct the sub-graphs in the linear time. As shown in the simulation results with MATLAB, compared with the classical algorithms, the new algorithm reduces significantly the time for constructing sub-graphs under ideal conditions.
