**Experimenter** for **I**terative **O**ptimization **H**euristics (IOHs), built in* `C++`.

* **Documentation**: [https://iohprofiler.github.io/IOHexperimenter](https://iohprofiler.github.io/IOHexperimenter).
* **Publication**: [https://arxiv.org/abs/1810.05281](https://arxiv.org/abs/1810.05281).
* **Wiki page**: [https://iohprofiler.github.io](https://iohprofiler.github.io/).

**IOHexperimenter** *provides*:

* A framework to ease the benchmarking of any iterative optimization heuristic.
* [Pseudo-Boolean Optimization (PBO)](https://iohprofiler.github.io/IOHproblem/) problem set (25 pseudo-Boolean problems).
* Integration of the well-known [Black-black Optimization Benchmarking (BBOB)](https://github.com/numbbo/coco) problem set (24 continuous problems).
* [W-model](https://dl.acm.org/doi/abs/10.1145/3205651.3208240?casa_token=S4U_Pi9f6MwAAAAA:U9ztNTPwmupT8K3GamWZfBL7-8fqjxPtr_kprv51vdwA-REsp0EyOFGa99BtbANb0XbqyrVg795hIw) problem sets constructed on OneMax and LeadingOnes.
* Integration of the [Tree Decomposition (TD) Mk Landscapes](https://github.com/tobiasvandriessel/problem-generator) problems.
* Submodular optimization problems, as seen in the [GECCO '22 workshop](https://cs.adelaide.edu.au/~optlog/CompetitionESO2022.php).
* Several benchmark suites from the CEC conference.
* Flexible interface for adding new suites and problems.
* Advanced logging module that takes care of registering the data in a seamless manner.
* Data format is compatible with [IOHanalyzer](https://github.com/IOHprofiler/IOHanalyzer).
* Dynamic BinVal functions ([paper](https://link.springer.com/article/10.1007/s42979-022-01203-z))
* Double funnel functions ([paper](https://link.springer.com/chapter/10.1007/978-3-540-87700-4_50))


**Available Problem Suites:**

* BBOB (Single Objective Noiseless) (COCO)
* SBOX-COST (COCO)
* StarDiscrepancy
* PBO
* Submodular Graph Problems
* CEC 2013 Special Session and Competition on Niching Methods for Multimodal Function Optimization
* CEC 2022 Special Session and Competition on Single Objective Bound Constrained Numerical Optimization
