• General Contact: iohprofiler@liacs.leidenuniv.nl
• Mailing List: https://lists.leidenuniv.nl/mailman/listinfo/iohprofiler

IOHexperimenter provides:

• A framework for straightforward benchmarking of any iterative optimization heuristic
• A suite consisting of 23 pre-made Pseudo-Boolean benchmarking function, with easily accessible methods for adding custom functions and suites
• Logging methods to effortlesly store benchmarking data in a format compatible with IOHanalyzer, with future support for additional data logging options
• (Soon to come:) A framework which significantly simplifies algorithm design

IOHexperimenter is built on:

• C++ (tested on gcc 5.4.0)
• boost.filesystem library for logging files.

IOHexperimenter is available for:

• C++
• R package https://github.com/IOHprofiler/IOHexperimenter/tree/R
• Python interface (soon to come)
• Java interface (soon to come)

Using IOHexperimenter

Running Experiments

The IOHexperimenter has been built on C++ and tested on complier gcc 5.4.0. To use the logging of csv output files, boost.filesystem library is required (To install boost library, please visit https://www.boost.org).

Using IOHexperimenter in C++

If you are using the tool for the first time, please download or clone this branch and run make at the root directory of the project. After running make to compile,

• object files will be generated in build/c/obj
• three exectuable files will be generated in build/c/bin

Afterwards, you can use the folder build/c and use the Makefile therein for your experiments. For more details of how to use the C++ version, please visit this page.

Using IOHexperimenter in R

To use the IOHexperimenter within R, please visit the R branch of this repository.

Creating test problems

Benchmarking problems in IOHexperimenter are easy to create yourself. We provide support for any input type and any number of real-valued objectives. For a more detailed guidline of how to define a benchmarking problem within IOHexperimenter, please visit this page.

Configuring test suites

Suites are collections of benchmarking problems. By including problems into a suite, it is easier for users to maintain their experiments. If you create a set of similar problems, it is recommended to create a suite to collect them together, which can be done effortlesly within the IOHexperimenter. For detailed steps of creating and using suites, please visit this page.
