Acceptance ratio of some Theoretical Computer Science Conferences

Here is a list of some acceptance rates of Theoretical Computer Science (TCS) Conferences (and some of computational biology). For each year, you can find the (Number Of Accepted Papers) / (Number Of Submitted Papers), and the corresponding ratio. These data are (manually) collected from the proceedings.

Obviously, the ratio doesn't mean anything about the conference quality or ranking (see for example this post of Lance Fortnow)! See also this interesting experiment on the conferences decisions, and this humoristic study.
Contact me for any remark or suggestion. See this page for AI conferences.
