Extension to submission date

To avoid overlap in conference deadlines, we have shifted the submission date for ACE to 23:59 13 October 2019, anywhere in the world. This is as late as we can push the deadline while maintaining the quality of the review process, so we will not be able to accept any papers submitted after that deadline.

Notably, this date is after the notifications are expected for both Koli 2019 and for SIGCSE 2020. For papers are rejected from either of those venues, we invite the authors to revise their manuscripts based on the feedback received during the review process and consider submitting the revised manuscript to ACE 2020.
