5th eCAS Workshop on Engineering Collective Adaptive Systems

 In conjunction with the 1st IEEE International Conference on Autonomic Computing and Self-Organizing Systems (ACSOS 2020, merger of the former ICAC and SASO conferences) ACSOS

Location: George Washington University Science and Engineering Hall, Washington DC, USA

Aims and Motivations

Modern computing systems are becoming ever more collective and are often composed of many distributed and heterogeneous entities. These systems operate under continuous perturbations and environmental change, making manual adjustments infeasible. For a collective system to be resilient, its adaptation must also be collective, in the sense that multiple entities must adapt in a way that addresses critical runtime conditions while preserving the benefits of collaborative interdependencies. Decision-making in such systems is distributed and possibly highly dispersed, and interaction between the entities may lead to the emergence of unexpected phenomena. In such systems, new approaches for and understanding of collective adaptation are needed, to allow: information multiple entities to adapt in a coordinated or complementary way, with (ii) negotiations, collective action, or other mechanisms to decide which collective changes are to be made. Collective adaptation also raises a second important challenge: Which parts of the system (things, services, people) should adapt, and how? This is nontrivial, as multiple solutions to the same problem may be generated at different levels, and individuals in the collective often have partial information. The challenge is to understand these levels and create mechanisms to decide the right scope for an adaptation for a given problem. This workshop solicits papers that address new methodologies, theories, principles, and fundamental understanding, that can be used to underpin the design, operation, and analysis of such systems. Case studies, applications showing such approaches in action, and interdisciplinary work are particularly welcome. 

Suggested Topics (but not limited to):

  • Novel theories relating to operating principles of CAS
  • Novel design principles for building CAS systems
  • Insights into the short and long-term adaptation of CAS systems
  • Insights into emergent properties of CAS
  • Insights into general properties of large scale, distributed CAS
  • Comparing and analyzing approaches to CAS (e.g., distributed and centralized)
  • Decision-making approaches in CAS
  • Methodologies for studying, analyzing, and building CAS
  • Frameworks for analyzing or developing CAS case studies
  • Languages, platforms, APIs and other tools for CAS
  • Scenarios, case studies, and experience reports of CAS in different contexts (e.g., Smart Mobility, Smart Energy/Smart Grid, Smart Buildings, traffic management, emergency response, etc.)


The workshop is expected to attract participants from many disciplines, including Autonomic Computing, Biology, Game Theory, Evolutionary Computing, Network Science, Self-Organizing Systems, Pervasive Computing, and to be of interest to anyone working with the domain of large-scale self-adaptive systems. In addition, the European Commission has funded seven scientific projects and a Coordination Action in this area, with projects starting at the beginning of 2013. The proposed workshop provides a natural base for the projects to meet and share ideas, yet we stress that the workshop is in no way limited to this audience, and is likely to have broad appeal to a wide range of researchers. Potential audience members might work in application areas relating to large-scale distributed systems, or may come from any of the many disciplines that can provide insights into the operation and design of such systems.

Important Dates

  • Workshop paper submission: June 19, 2020 (extended!)
  • Workshop paper notification: June 30, 2020
  • Camera-Ready Version: July 8, 2020
  • Workshop: August 21, 2020

Submission Details and Review Process

Contributions will be peer reviewed for originality, clarity and readability, relevance to themes, soundness, and overall quality. We solicit the following types of contributions:

  • Workshop papers, limited to 6 pages including references, following the IEEE Computer Society Press proceedings style guide.
  • Talks, submitted as extended abstracts, limited to 1 page including references, without formatting restrictions.

Workshop papers will be published on IEEE Xplore in parallel with the main IEEE ACSOS conference proceedings. Extended abstracts will not be published, should be relevant to the eCAS community (with a preference for application-focussed talks or lessons learnt) and may report information on work having already been (partially) presented elsewhere, or (ii) work at an early stage, where there would be benefit for both the authors and audience in sharing ideas and progress. All contributions should be submitted in PDF format using the Easychair login page:


By submitting, the authors confirm that in case of acceptance, at least one author will present the work at the workshop.

Statement Regarding COVID-19

The eCAS and ACSOS Steering and Organizing Committees have been monitoring the situation surrounding COVID-19, and considering what impact this may have on events scheduled for later in the year, such as ours. eCAS will follow the arrangements of the main ACSOS conference. We would like to express our empathy and condolences with those affected by COVID-19 so far, and those who will have a difficult 2020. Our primary concern is that members of our community, and their families and friends, remain safe and well. We are aware of the restrictions and uncertainty that people are facing, and therefore want to take this opportunity to announce and confirm that:

  • eCAS and ACSOS will take place, and on their original dates in August.
  • There will be an opportunity to present virtually, for anyone who cannot or chooses not to travel.
  • All accepted eCAS papers will be published in the workshops proceedings by IEEE, regardless of whether a physical or virtual presentation is given.
  • Whether the workshop becomes entirely virtual or a hybrid is a decision that will be taken by early June at the latest. This is to ensure people have ample time to make travel arrangements, in the case of physical attendance.

As the situation surrounding COVID-19 is evolving rapidly, it is unclear what things will be like in the late summer. Therefore, we hope you find the above clarifications helpful, and we appreciate your understanding as we continue to monitor the situation carefully.
