FSEN is an international conference that aims to bring together researchers, engineers, developers, and practitioners from the academia and the industry to present and discuss their research work in the area of formal methods for software engineering. This conference seeks to facilitate the transfer of experience, adaptation of methods, and where possible, foster collaboration among different groups. The topics of interest cover all aspects of formal methods, especially those related to advancing the application of formal methods in the software industry and promoting their integration with practical engineering techniques.
