ParamILS: Software

ParamILS version 2.3.4 [source, executables and examples] [quick start guide]. Minor bugfix removing the need for a "-I" parameter when calling ParamILS from source. Users should now be able to call ParamILS from whatever working directory they like.
ParamILS version 2.3.3 [source, executables and examples] [quick start guide]. This is another bugfix release, in order to rectify a problem experienced when trying to run ParamILS under Windows. This is a joint release of the source along with binaries for Linux and Windows.
ParamILS version 2.3.2 [executable and examples] [complete source] [quick start guide]. This is another bugfix release, fixing a bug when tuning deterministic solvers when the -N parameter is unspecified. Tuning runs should be unchanged for other scenarios. Also contains some merged and cleaned up code from Frank Hutter.
ParamILS version 2.3.1 [executable and examples] [complete source] [quick start guide]. This is another bugfix release, in order to fix a problem where timed out runs were penalised by a factor of 10 when tuning for runtime, even when overall_obj was set to 'mean' and not 'mean10'. Scenarios not tuning for runtime should be unaffected.
ParamILS version 2.3 [executable and examples] [complete source] [quick start guide]. Version 2.3 is a bugfix release, correcting a problem that would cause ParamILS to try and access a database regardless of the value passed with the -db flag.
ParamILS version 2.2 [executable and examples] [complete source]. There is a new new quick start guide (updated Aug 1, 2008) that covers the much improved user interface.
The zip file also contains examples enabling you to tune all the algorithms we cover in our journal article on ParamILS submitted to JAIR.
Version 2.2 is idential to 2.1 except that the user-interface has been simplified: users no longer have to generate instance-seed files, and also have the option to define their tuning scenario in an input file (for later reuse)
ParamILS version 2.1 (zip, 105KB). This release is to ensure repeatability of experiments: it is the modified version used for the self-tuning experiments in our journal article on ParamILS submitted to JAIR
In version 2.1, the inefficient internal caching mechanism inside the ParamILS scripts has been addressed (for tuning scenarios where single algorithm runs are well below a second, the time
spent for ParamILS's internal bookkeeping became substantial compared to the time spent running algorithms).
Unfortunately, since Hashes are indexed differently now, version 2.1 will not return the exact same result as version 2.0, even with identical seeds.
(Means and standard deviations of 25 runs are, however, virtually the same as for version 2.0)
ParamILS version 2.0 (zip, 109KB). This release is to ensure repeatability of experiments: it is the version used for the experiments in our journal article on ParamILS submitted to JAIR.
Version 2.0 introduced major changes to enable Bound & Prune, our technique for early pruning of unsuccesful runs.
ParamILS version 1.0 (tar.bz2, 440KB). The tar.gz file also contains a quick start guide that should help you apply it to your algorithms.
