Research on Agents and Multi-Agent Systems has matured during the last decade and many effective applications of this technology are now deployed. SARL-18 provides an international forum to present and discuss the latest scientific developments and their effective applications, to assess the impact of the approach, and to facilitate technology transfer.SARL-18 borns with the SARL agent programming language, but the scientific results presented in SARL-18 are not restricted to SARL; other languages and agent platforms may be presented.SARL aims at providing the fundamental abstractions for dealing with concurrency, distribution, interaction, decentralization, reactivity, autonomy and dynamic reconfiguration. These high-level features are now considered as the major requirements for an easy and practical implementation of modern complex software applications. We are convinced that the agent-oriented paradigm holds the keys to effectively meet this challenge. Considering the variety of existing approaches and meta-models in the field of agent-oriented engineering and more generally multi-agent systems, our approach remains as generic as possible and highly extensible to easily integrate new concepts and features.The goal of SARL-18 is to provides a place where the different points of view on the modeling and the simulation with agent platforms and agent programming languages may be discussed.SARL-18 will be held in Porto, Portugal (8-10 May 2018) in conjunction with the 9th International Conference on Ambient Systems, Networks, and Technologies (ANT 2018).
