Artifact Archive for memo-regex This is the artifact archive for "Efficient Matching with Memoization for Regexes with Look-around and Atomic Grouping". This includes the following artifacts: source codes of the memo-regex implementation copies of the results of the experiments described in the paper scripts for reproducing the results of the experiments memo-regex is a linear-time regex matching implementation with memoization. It is an implementation of the algorithm described in the paper and supports look-around operators and atomic grouping. These artifacts relate to the content of §6 of the paper. This archive contains the source code for the implementation described in §6.1, the result data of Figures 7 and 8 in §6.2, and the data of Table 3 in §6.3.
