Optimization of LR(k) parsers

摘要

Certain techniques for modifying LR(k) parsing tables to decrease their size have been developed by Korenjak [2] and DeRemer [3, 4]. We show that the techniques of the latter can be characterized by two transformations on sets of tables. We then show that the “simple” LR(1) method of DeRemer [4] can be considered a special case of Korenjak's method [2].
