Ensemble-Based Software Engineering for Modern Computing Platforms

Software systems have evolved from being 'stand-alone systems' to 'systems of systems' to meet the challenging needs of societies. Contemporary software systems such as socio-technical systems are composed of distributed and heterogeneous agents, the em- bedded environment, and software components. Addressing the disruptions caused by run-time changes in the environment while designing software systems remains a challenging task in practice. Ensembles enable systems with collective adaptability to be built as emergent aggregations of autonomous and self-adaptive agents. The phenomenal aspect of this type of systems allows agents (i.e, services, people and things) a ected by an issue to adapt collabo- ratively with minimal impact on their own preferences through a collective resolution process. In this paper we report the outcomes of the 2nd ACM SIGSOFT International Workshop on Ensemble- Based Software Engineering for Modern Computing Platforms (EnSEmble 2019), which was held as part of the 27th ACM Joint European Software Engineering Conference and Symposium on the Foundations of Software Engineering (ESEC/FSE 2019) in Tallinn, Estonia, on August 26th, 2019.
