Abstract:
PURPOSE: A dynamic LCNSS searching method based on a prefix graph model is provided to rapidly and efficiently search LCNSS by modifying a peak point and a main point corresponding to a letter string which is added or deleted to the combination of a forbidden letter string. CONSTITUTION: A prefix graph which is generated by a forbidden string set is reconfigured by generating a peak point and a main point corresponding to the letter string which is added to the forbidden letter string set(S100). A LCNSS(Longest Common Non-Superstring) corresponding to the longest letter string is searched by using the reconfigured prefix graph(S300). The prefix graph is reconfigured by searching a peak point corresponding to the added letter string in the prefix graph. If the peak point corresponding to the added letter string does not exists in the prefix graph, the peak point and the main point corresponding to the added letter string is generated to the prefix graph.
Abstract:
PURPOSE: A method for finding longest common non-superstrings is provided to rapidly and efficiently search the longest common emergency character string by creating suffix graph model. CONSTITUTION: A suffix graphs is created using a suffix array about the character string group. The longest common non-superstring is searched using the suffix graph. The suffix graph creates a generalized suffix array which arranges the suffix of each character string in a dictionary order, creates the vertex set and an arterial line, and links the arterial lines(230).
