prechelt-phone-number-encoding | Common Lisp solutions to a phone-encoding problem

prechelt-phone-number-encoding is a Java library. prechelt-phone-number-encoding has no bugs, it has no vulnerabilities and it has low support. However prechelt-phone-number-encoding build file is not available. You can download it from GitHub.

This project implements the phone number encoding described by Lutz Prechelt in his article for the COMMUNICATIONS OF THE ACM (October 1999/Vol. 42, No. 10), Comparing Java vs. C/C++ Efficiency Differences to Interpersonal Differences, later re-used for a more extended paper, An empirical comparisonofC, C++, Java,Perl, Python, Rexx, and Tclfor asearch/string-processing program from March, 2000. The same problem was later used by Ron Garret (aka Erann Gat) on Lisp as an alternative to Java, also from the year 2000. The instructions given to participants of the latter study (which was slightly adapted from the original paper, and used to implement my own solution in this repository) can be found at flownet.com. Peter Norvig, after finding out about the Lisp paper, wrote his own Lisp program to solve the problem. His solution is included in this repository at src/lisp/main.lisp as a baseline for performance measurements (see benchmark.sh).
