SSBSE 2017 is the ninth edition of the annual symposium dedicated to Search Based Software Engineering. SBSE studies the application of meta-heuristic optimization techniques to various software engineering problems, ranging from requirements engineering to software testing and maintenance. The symposium provides a welcoming forum for discussion and dissemination that will strengthen the rapidly-growing international SBSE community.

Research papers must have up to 15 pages in length, including all text, figures, references, and appendices. For all other papers, submissions should not exceed 6 pages in length (using the regular symposium format).
