AbstractSwarm Multi-Agent Logistics Competition

Description:

This competition aims to motivate work in the broad field of logistics. We have prepared a benchmarking framework which allows the development of multi-agent swarms to process a variety of test environments. Those can be extremely diverse, highly dynamic and variable of size. The ultimate goal of this competition is to foster comparability of multi-agent systems in logistics-related problems (e. g., in hospital logistics). Many such problems have good accessibility and are easy to comprehend, but hard to solve. Problems of different diffculty have been designed to make the framework interesting for educational purposes. However, finding effcient solutions for different a priori unknown test environments remains a challenging task for practitioners and researchers alike.
Following these ideas, in the AbstractSwarm Multi-Agent Logistics Competition, participants must develop agents that are able to cooperatively solve different a priori unknown logistics problems. A logistics problem is given as a graph containing agents and stations. An agent can interact with the graph (1) by deciding which station to visit next, (2) by communicating with other agents, and (3) by retrieving a reward for its previous decision. While simulating a scenario, a timetable in the form of a Gantt-chart is created according to the decisions of all agents. Submissions will be ranked according to the total number of idle time of all agents in several different a priori unknown problem scenarios in conjunction with the number of iterations needed to come to the solution.

Competition on Real Parameter Single Objective Bound Constrained Optimization

Description:

The goals are to evaluate the current state of the art in single objective numerical optimization with bound constraints with an increased number of maximum function evaluations. In the past, a maximum number of function evaluations did not scale with increasing dimensions while the complexity of the problems increased exponentially with the increasing dimensions. In addition, we will also consider several transformations such as translation, rotation, shearing, etc. in order to highlight the importance of these transformations. Although there are 100s of newly proposed metaheuristics in recent years, most have been evaluated on classical problems without rotation and with the global solution at the origin or very near the origin. We anticipate that this benchmark will help identify metaheuristics with various built-in biases to solve the classical problems effectively. In addition, we will also propose a novel scoring method to compare the algorithms.

Dynamic Stacking Optimization in Uncertain Environments

Description:

Stacking problems are central to multiple billion-dollar industries. The container shipping industry needs to stack millions of containers every year. In the steel industry the stacking of steel slabs, blooms, and coils needs to be carried out efficiently, affecting the quality of the final product. The immediate availability of data – thanks to the continuing digitalization of industrial production processes – makes the optimization of stacking problems in highly dynamic environments feasible.

There are two tracks in this competition, same as in the last competition.
In the first track a dynamic environment is provided that represents a simplified stacking scenario. Blocks arrive continuously at a fixed arrival location from which they have to be removed swiftly. If the arrival location is full, the arrival of additional blocks is not possible. To avoid such a state, there is a range of buffer stacks that may be used to store blocks. Each block has a due date before which it should be delivered to the customer. However, blocks may leave the system only when they become ready, i.e., some time after their arrival. To deliver a block it must be put on the handover stack – which must contain only a single block at any given time. There is a single crane that may move blocks from arrival to buffer, between buffers, and from buffer to handover. The optimization must control this crane in that it reacts to changes with a sequence of moves that are to be carried out. The control does not have all information about the world. A range of performance indicators will be used to determine the winner.
The second track represents another stacking scenario that is derived from real-world scenarios. It features two cranes and two different handovers. The cranes have a capacity of larger than one which represents an additional challenge for the solver. The solver may just provide the moves and the cranes will sort out the order in which these are performed (not optimal though) or the solver may optimize both the moves and the assignment and schedule of the cranes. In this scenario, not the arrival stack is the critical part, but the handover stacks and thus the downstream process must not run empty.

The dynamic environments are implemented in form of a realtime simulation which provides the necessary change events. The simulation runs in a separate process and publishes its world state and change events via message queuing (ZeroMQ), and also listens for crane orders. Thus, control algorithms may be implemented as standalone applications using a wide range of programming languages. Exchanged messages are encoded using protocol buffers – again libraries are available for a large range of programming languages. As in the 2021 competition a website will be used that participants can use to create experiment and test their solvers. In addition, the simulation models are available at GitHub for offline testing and development at https://github.com/dynstack/dynstack. We gladly accept pull requests for new starter kits, existing algorithms and approaches, as well as additions to the bibliography on works that have used the competition for scientific research.

Evolutionary Computation in the Energy Domain: Risk-based Energy Scheduling

Description:

Following the success of the previous editions at IEEE PES; CEC; GECCO, WCCI, we are launching another challenging edition of competition at major conferences in the field of computational intelligence. This edition of GECCO 2022 competition proposes one track in the energy domain:

Track 1) Risk-based optimization of aggregators’ day-ahead energy resource management (ERM) considering uncertainty associated with the high penetration of distributed energy resources (DER). This test bed is constructed under the same framework of past competitions (therefore, former competitors can adapt their algorithms to this new track), representing a centralized day-ahead ERM in a smart grid with a 13-bus distribution network using a 150-scenario case study with 10 scenarios considering extreme events (high impact, and low probability). A conditional value-at-risk (CVaR) mechanism is used to measure the risk associated with the extreme events for a confidence level (α) of 95%. We also add some restrictions to the initialization of the initial solution and the allowed repairs and tweak-heuristics.

Note: The track is developed to run under the same framework of past competitions.

Competition goals:
The GECCO 2022 competition on “Evolutionary Computation in the Energy Domain: Risk-based Energy Scheduling” has the purpose of bringing together and testing the more advanced Computational Intelligence (CI) techniques applied to energy domain problems, namely a risk-based optimal day-ahead ERM considering the uncertainty associated with high penetration of DER. The competition provides a coherent framework where participants and practitioners of CI can test their algorithms to solve a real-world optimization problem in the energy domain. The participants have the opportunity to evaluate if their algorithms can rank well in the proposed problem since we understand the validity of the “no-free lunch theorem”, making this contest a unique opportunity worth to explore the applicability of the developed approaches in a real-world problem beyond the typical benchmark and standardized CI problems.

Evolutionary Submodular Optimisation

Description:

Submodular functions play a key role in the area of optimisation as they allow to model many real-world optimisation problem. Submodular functions model a wide range of problems where the benefit of adding solution components diminishes with the addition of elements. They form an important class of optimization problems, and are extensively studied in the literature. Problems that may be formulated in terms of submodular functions include influence maximization in social networks, maximum coverage, maximum cut in graphs, sensor placement problem, and sparse regression. In recent years, the design and analysis of evolutionary algorithms for submodular optimisation problems has gained increasing attention in the evolutionary computation and artificial intelligence community.

The aim of the competition is to provide a platform for researchers working evolutionary computing methods and interested in benchmarking them on a wide class of combinatorial optimization problems.
The competition will benchmark evolutionary computing techniques for submodular optimisation problems and enable performance comparison for this type of problems. It provides an idea vehicle for researchers and students to design new algorithms and/or benchmark their existing approaches on a wide class of combinatorial optimization problems captured by submodular functions.

The description of the benchmark and evaluation process will be available on the competition webpage (by latest 15 April 2022).

Interpretable Symbolic Regression for Data Science

Description:

Symbolic regression methods have made tremendous advances in the past decade, and have recently gained interest as the broader scientific community has recognized the importance of interpretable machine learning. Despite this, there is little agreement in the field about which algorithms are “state-of-the-art”, and how to best design symbolic regression methods for use in the real world. This competition seeks to distill algorithmic design choices and improve the practice of symbolic regression by evaluating the submitted symbolic regression methods on previously unseen, real-world and synthetic datasets. These datasets will be sourced mainly from the domains of physics, epidemiology and bioinformatics.

Participants are asked to adapt and submit their symbolic regression algorithms to SRBench, following the contributing guidelines. SRBench will automatically test these methods for conformance with the competition.

After the submission deadline, methods will be tested on previously unseen datasets. These datasets cover synthetic and real-world problems, and in each case, either an exact model or a human-designed model will be used for comparison. Notice that these will be new benchmarks specifically curated for this competition. The current version of SRBench will serve as a first-pass filter for candidate entries. As such, participants are free to test and fine-tune their algorithms on the current version of SRBench. Algorithm submissions will be judged by their ability to discover the ground-truth models, or, in the case of real-world data, approximate or outperform the expert models with similar or lower complexity. Winners will be determined based on the accuracy and simplicity of the generated models, both individually and in the Pareto efficient sense. After competition, the submitted methods, evaluation procedure, and new datasets will be made publicly available.

Minecraft Open-Endedness Challenge

Description:

The purpose of the second contest on open-endedness is to highlight the progress in algorithms that can create novel and increasingly complex artefacts. While most experiments in open-ended evolution have so far focused on simple toy domains, we believe Minecraft -with its almost unlimited possibilities- is the perfect environment to study and compare such approaches. While other popular Minecraft competitions, like MineRL, have an agent-centric focus, in this competition the goal is to directly evolve Minecraft builds.

As part of this competition, we introduce the EvoCraft API. EvoCraft is implemented as a mod for Minecraft that allows clients to manipulate blocks in a running Minecraft server programmatically through an API. The framework is specifically developed to facilitate experiments in artificial evolution. The competition framework also supports the recently added "redstone" circuit components in Minecraft, which allowed players to build amazing functional structures, such as bridge builders, battle robots, or even complete CPUs. Can an open-ended algorithm running in Minecraft discover similarly complex artefacts automatically?

In addition to the general Open-Ended competition, we will add an Open-Ended Play track. With this track, we would like to encourage research that leads to new and surprising Minecraft machines, that more directly make use of the unique Minecraft physics. Here agents must build Minecraft machines to score a goal against their opponent, which must build machines to counter it, while simultaneously trying to score their own goal, all with a limited budget of blocks.

Optimization of a simulation model for a capacity and resource planning task for hospitals under special consideration of the COVID-19 pandemic

Description:

Similar to the many previous competitions, the team of the Institute of Data Science, Engineering, and Analytics at the TH Cologne (IDE+A), hosts the 'Industrial Challenge' at the GECCO 2022.
Based on the 2021 GECCO industrial challenge an updated more advanced problem is provided. This year’s industrial challenge is again in cooperation with an IDE+A partner from health industry and with Bartz & Bartz GmbH.

Simulation models are valuable tools for resource usage estimation and capacity planning. Your goal is to determine improved simulation model parameters for a capacity and resource planning task for hospitals. The simulator, babsim.hospital, explicitly covers difficulties for hospitals caused by the COVID-19 pandemic. The simulator can handle many aspects of resource planning in hospitals:
- various resources such as ICU beds, ventilators, personal protection equipment, staff, pharmaceuticals
- several cohorts (based on age, health status, etc.).

The task represents an instance of an expensive, high-dimensional computer simulation-based optimization problem and provides an easy evaluation interface that will be used for the setup of our challenge. The simulation will be executed through an interface and hosted on one of our servers (similar to our last year's challenge).
The task is to find an optimal parameter configuration for the babsim.hospital simulator with a very limited budget of objective function evaluations. The best-found objective function value counts. There will be multiple versions of the babsim.hospital simulations, with slightly differing optimization goals, so that algorithms can be developed and tested before they are submitted for the final evaluation in the challenge.
The participants will be free to apply one or multiple optimization algorithms of their choice.
Thus, we enable each participant to apply his/her algorithms to a real problem from health industry, without software setup or licensing that would usually be required when working on such problems.

SpOC: Space Optimisation Competition

Description:

SpOC (Space optimisation Competition) is a new optimisation competition proposed by the
Advanced concepts Team of the European Space Agency in the context of GECCO 2022. The
competition will have several teams of experts around the word compete to find the best solution to
multiple optimization problems applied to advanced space scenarios, with a focus on metaheuristics
and black-box optimization.
Several highly complex optimisation problems will be simultaneously released and submitted to the
scientific community who will have roughly one month to solve them. Participants will compete to
find the best solution for each individual problem, but also to be the best overall team. Similar to
multi-sport events, SpOC will award global points to the best performing teams for each problem.
These points will be used to establish a global ranking that will decide the winner of the competition.
In short, if GTOC is the America’s Cup of trajectory optimization, SpOC aims to be the Ironman race
of space optimization.
Each individual problem will be inspired by a promising advanced space concept and a global
inspiring context will be provided for the competition. All problems will differ in nature and
objective, so that a single solution approach should not be easily applicable to all of them, and be
complex enough to make for a challenging competition . The organizers may provide if needed a
codebase for the participants to be used as a black-box for output analysis and optimization.
The competition will be open to everybody worldwide. The target audience for the challenge is
experienced aerospace engineers and mathematicians but graduate students are also highly
encouraged to participate.
