Dataset Generator

A porting to C++11 and modern g++ of the IBM Quest dataset generator.

History

Once upon a time (possibly on July 22 1997), the IBM Almaden group published a synthetic transactional dataset generator. The workings of the generator were described in 'R. Agrawal and R. Srikant. Fast algorithms for mining association rules in large databases. In Proc. 20th Int. Conf. Very Large Data Bases, VLDB ’94, pages 487–499, 1994'. The original version could be downloaded from http://www.almaden.ibm.com/cs/quest/syndata.html (that page no longer exists).

After a while (around 2002-2003), the IBM version could not be compiled with "modern" g++ compilers anymore. Paolo Palmerini ([email protected]) published a g++-compilable modified version of the generator on his website (also no longer existed). Paolo's modifications can be found in the source code by looking for comments highlighted by "// g++".

As of June 2014 Paolo's version does not compile on current g++ (e.g., g++-4.9). Matteo Riondato ([email protected]) took up the task to port the code to C++11 and make it compile with the current g++.

Install

Just run "make" and the code will be compiled. It uses whatever "g++" is on your system. You can specify your favourite version by modifying the Makefile.

datasetgenerator's Issues

Sefault in choose.h

Choose::num is never initialized to have a certain size, and so the subsequent accesses are segfaulting.

Proposed solution: change line 14 from Choose(LINT n, LINT k) { to Choose(LINT n, LINT k) : num(n) {

Does not compile using latest

Compilation fails on Mac OS High Sierra using latest XCode command line tools.

Could you help?

Thanks
