Addibit is Another Double Description Implementation with BInary Trees. It supports the following adjacency test variants:
  • combinatorial test using bit pattern trees [1,2] (bp-trees),
  • combinatorial test using bit pattern trees and query bits neutralization (bp-qbn-trees),
  • combinatorial test using vantage point trees [3] (vp-trees),
  • algebraic test using the Gauss elimination method, and
  • algebraic test using active set partitioning.
The current version is 0.3.0 (alpha) which may (and surely does) contain a lot of bugs. Check the README-file for instructions of how to compile and run the program. For an overview of the double description method, we refer to [4]. Here is a small study comparing the performance of the different combinatorial test variants.
The archive package contains statically compiled versions of the noncommercial tools four-ti-two, cddr, polco, porta, ppl, skeleton and lrs. Using the script benchmark.sh, you can run addibit and the other tools on a set of arbitrary problems. Prepared problems can be found in the archive (see folder experiments).
