The "ACMS 20" is ambiguous as it could refer to different conferences or events with the acronym ACMS or ACM. Here are the relevant findings:
- The 20th ACM Asia Conference on Computer and Communications Security (ACM ASIACCS 2025) is scheduled for August 25-29, 2025, in Hanoi, Vietnam.
- The 20th Annual Meeting (ACM20) of a certain ACM-related organization was held November 27-29, 2023, at Sahira Hotel, Bogor, West Java.
If the question is about the 20th ACM ASIACCS conference, it is happening August 25-29, 2025. If it is about the 20th Annual Meeting related to ACM (possibly a different organization), it took place in November 2023. Please clarify if you were referring to a specific ACMS or ACM event for more precise details.
