| Research Abstract |
The purpose of this research is to develop algorithms and data structure for efficient term matching and rewriting. The results obtained are as follows.
1. We propose three algorithms for tree-pattern matching. By preprocessing the pattern, the first one performs efficient matching. The second one is very efficient when the pattern contains few variables. The last one is a parallel algorithm based on a systolic array.
2. We design an efficient parallel algorithm on PRAM. The algorithm runs in O (log n) time using (mn/log n) processors, where m and n are sizes of input pattern and text, respectively.
3. We investigate implementation methods of the parallel outermost rewriting strategy in TRS.
4. We published the above results as a research report.
