This book constitutes the refereed proceedings of the tracks and workshops which complemented the 14th European Conference on Software Architecture, ECSA 2020, held in L'Aquila, Italy*, in September 2020. The 30 full papers and 9 short papers presented in this volume were carefully reviewed and selected from 72 submissions. Papers presented were accepted into the following tracks and workshops: ECSA 2020 Doctoral Symposium track; ECSA 2020 Tool Demos track; ECSA 2020 Gender Diversity in Software Architecture &Software Engineering track; CASA - 3rd International Workshop on Context-aware, Autonomous and Smart Architecture; CSE/QUDOS - Joint Workshop on Continuous Software Engineering and Quality-Aware DevOps; DETECT - 3rd International Workshop on Modeling, Verication and Testing of Dependable Critical Systems; FAACS-MDE4SA - Joint Workshop on Formal Approaches for Advanced Computing Systems and Model-Driven Engineering for Software Architecture; IoT-ASAP - 4th International Workshop on Engineering IoT Systems: Architectures, Services, Applications, and Platforms; SASI4 - 2nd Workshop on Systems, Architectures, and Solutions for Industry 4.0; WASA - 6th International Workshop on Automotive System/Software Architecture. *The conference was held virtually due to the COVID-19 pandemic.

This work follows quite recent discovery that even very complex phenomena common in nature can emerge from interaction of a large number of agents following very simple behavioural rules, reflected in the automata-based fashion. After discussion of an appropriate methodology for examining models defined in this way, the thesis specifies, models, examines and interprets a selected economic system (fundamentalist/chartist stock market) in terms of simple interacting automata, and uses this experimental study to practically evaluate the strengths and weaknesses of the approach. This work should be especially useful to professionals in agent-based computational economics, helping them to get to the heart of automata models of economic agents, and providing them with guidelines of automata-based modelling and analysis in this context.
