Abstract: The characteristic of Quaternary codes is analyzed. The rule of distinguishing triangle direction is given out.The algorithm of neighbor finding from back to front with decomposing Quaternary code is presented.The analysis of time complexity between this decomposing algorithm and bartholdi's algorithm is approached.The result is that average consumed time of this decomposing algorithm is about 23.66% of Bartholdi's.
