Black Box Optimization Competition
The Black Box Optimization Competition is the first competition platform in the continuous domain where test problems are truly black boxes to participants. The only information known to the optimizer and participant is the dimension of the problem, bounds on all variables, and a budget of black box queries.
The competition is also the first web/online optimization competition in evolutionary computation domain. It aims at attacking a growing impact of over-fitting of optimization algorithms to a narrow set of existing benchmark problems. The competition was run three times with a total of 100 submissions.
Submission deadline:June 30, 2017

His research is located in the areas of supervised machine learning and optimization in continuous spaces, in particular with evolution strategies. His work on randomized search heuristics is focused on natural evolution strategies (NES) as well as on multi-objective optimization.
Industrial Challenge: Monitoring of drinking-water quality
Water covers 71% of the Earth's surface and is vital to all known forms of life. The provision of safe and clean drinking water to protect public health is a natural aim. Performing regular monitoring of the water-quality is essential to achieve this aim.
Goal of the GECCO 2017 Industrial Challenge is to analyze drinking-water data and to develop a highly efficient algorithm that most accurately recognizes diverse kinds of changes in the quality of our drinking-water.

MicroRTS AI Competition
Several AI competitions organized around RTS games have been organized in the past (such as the ORTS competitions, and the StarCraft AI competitions), which has spurred a new wave of research in to RTS AI. However, as it has been reported numerous times, developing bots for RTS games such as StarCraft involves a very large amount of engineering, which often relegates the research aspects of the competition to a second plane. The microRTS competition has been created to motivate research in the basic research questions underlying the development of AI for RTS games, while minimizing the amount of engineering required to participate. Also, a key difference with respect to the StarCraft competition is that the AIs have access to a "forward model" (i.e., a simulator), with which they can simulate the effect of actions or plans, thus allowing for planning and game-tree search techniques to be developed easily. Although we acknowledge that planning in domains for which the agent does not have a forward model is a very important problem, this is left out of this competition, in order to focus on other core RTS problems.

Niching Methods for Multimodal Optimization
The aim of the competition is to provide a common platform that encourages fair and easy comparisons across different niching algorithms. The competition allows participants to run their own niching algorithms on 20 benchmark multimodal functions with different characteristics and levels of difficulty.
Researchers are welcome to evaluate their niching algorithms using this benchmark suite, and report the results by submitting a paper to the main tracks of GECCO 2017 (i.e., submitting via the online submission system of GECCO 2017). The description of the benchmark suite, evaluation procedures, and established baselines can be found in the following technical report:
X. Li, A. Engelbrecht, and M.G. Epitropakis, ``Benchmark Functions for
CEC'2013 Special Session and Competition on Niching Methods for Multimodal
Function Optimization'', Technical Report, Evolutionary Computation and
Machine Learning Group, RMIT University, Australia, 2013.
The test suite for the competition and the performance measures are implemented in Matlab, Java, Python and C++, and will be available for download from the competition website (URL will be provided later). Notice that, apart from the benchmark function suite, the competition facilitates the evaluation and comparison of different niching algorithms. The procedures
developed takes into consideration two main objectives: 1) the test suite should be simple to use; and 2) the test suite can be used to facilitate fair comparisons of different niching algorithms. The procedure should be easy to follow since user interaction with unnecessary details will be kept at minimal. This will allow interested researchers to focus their effort primarily on the development of state-of-the-art niching algorithms. A framework with such facilities has already proved to be valuable to the research community and has led to major developments of the field, e.g., the Black-Box Optimization Benchmark (BBOB) competition organized at GECCO each year.

Optimisation of Problems with Multiple Interdependent Components
Real-world optimization problems often consist of several NP-hard combinatorial optimization problems that interact with each other. Such multi-component optimization problems are difficult to solve not only because of the contained hard optimization problems, but in particular, because of the interdependencies between the different components. Interdependence complicates a decision making by forcing each sub-problem to influence the quality and feasibility of solutions of the other sub-problems. This influence might be even stronger when one sub-problem changes the data used by another one through a solution construction process. Examples of multi-component problems are vehicle routing problems under loading constraints, the maximizing material utilization while respecting a production schedule, and the relocation of containers in a port while minimizing idle times of ships.
The goal of this competition is to provide a platform for researchers in computational intelligence working on multi-component optimization problems. The main focus of this competition is on the combination of Traveling Salesperson and Knapsack problems. However, we plan to extend this competition format to more complex combinations of problems (that have typically been dealt with individually in the past decades) in the upcoming years.
The set of benchmarks used in this competition follows the idea of the "Travelling Thief Problem" (Mohammad Reza Bonyadi, Zbigniew Michalewicz, Luigi Barone: The travelling thief problem: The first step in the transition from theoretical problems to realistic problems. IEEE Congress on Evolutionary Computation 2013). Eucledian 2D Traveling Salesperson instances are combined with 0-1-Knapsack instances in such a way that it reflects aspects of problems from the real-world; for example, the total weight of the items in the knapsack influences the travel speed of a traveller. This introduced interdependence sets our benchmarks apart from capacitated vehicle routing problem instances, where this interdependence does not exist. For technical details on how the benchmarks were created, please see the manual (Sergey PoIyakovskiy, Mohammad Reza Bonyadi, Markus Wagner, Frank Neumann, and Zbigniew Michalewicz: A Comprehensive Benchmark Set and Heuristics for the Traveling Thief Problem. Genetic and Evolutionary Computation Conference 2014). Some related work can be found at the University of Adelaide’s TTP Project Page (http://cs.adelaide.edu.au/~optlog/research/ttp.php).
All 9720 instances are available for researchers to experiment with: http://cs.adelaide.edu.au/~optlog/CEC2014COMP_InstancesNew/
In order to encourage researchers during the weeks before the submission deadline, we invite them to submit solutions for a few selected sample instances. These results will be displayed online (without a reference to the authors) and then will serve as performance indications for other researchers. An example of how this informal ladder for a single instance can look like:
In contrast to previous years, we will not run the code, and we will also not impose any resource limits. The participants will send us the solutions (one solution per instance) in the pre-defined format. This relaxation has the advantage that researchers are no longer bounded by the established “10 minutes of 1 CPU core”, opening up the research on multi-component problems to new approaches.
Track 1: The original TTP formulation is used.
Track 2: A relaxed TTP formulation is used, in which not all cities need to be visited and more than one thief can be used (Shelvin Chand, Markus Wagner: Fast Heuristics for the Multiple Traveling Thieves Problem. Genetic and Evolutionary Computation Conference 2016).
In both tracks, the same 9720 instances will be used.
Markus Wagner provides AUD 1000 in cash. Additional sponsors are being sought right now.
