若下一轮比对将从T[i]与P[t]的比对开始,这等效于将P右移j - t个单元,位移量与t成反比。因此,为保证P与T的对齐位置(指针i)绝不倒退,同时又不致遗漏任何可能的匹配,应在集合N(P, j)中挑选最大的t。也就是说,当有多个值值得试探的右移方案时,应该保守的选择其中移动距离最短者,于是,令next[j] = ...
We consider the problem of linear regular tree pattern matching and describe a new solution based on a bottom up technique. Current bottom up techniques preprocess the patterns and construct a finite state tree pattern matching automaton for the purpose. Though matching time is linear in the size...
Based on the discussion of BM and BMHS algorithm for pattern matching,an improved algorithm named FSBM is presented in this paper.This algorithm uses the information carried by the character next after the current window and the matching information inside the current window so as to increase the...
Some authors therefore proposed pattern matching algorithms that directly support DAG structures. In [51] a code selection algorithm was presented that can generate optimal vertical code for DAG's, on a processor with only a single register. In [61] this algorithm has been further refined to ...
Fast and Scalable Pattern Matching for Network Intrusion Detection Systems High-speed packet content inspection and filtering devices rely on a fast multipattern matching algorithm which is used to detect predefined keywords or si...

We propose a fast tree pattern matching algorithm called TreeMatch to directly find all distinct matchings of a query tree pattern. The only requirement for the data source is that the matching elements of the non-leaf pattern nodes do not contain subelements with the same tag. The TreeMatch ...
12 presented an algorithm for detecting welds at butt joints with an arc welding robot using computer vision. The method automatically subtracts the background from images obtained by a robot-mounted camera system. It can detect straight and curved welds without prior knowledge of the weld ...
