About

The goal of this wiki is to collate a set of open problems in sub-linear algorithms and to track progress that is made on these problems. Important topics within sub-linear algorithms include data stream algorithms (sub-linear space), property testing (sub-linear time), and communication complexity (sub-linear communication) but this list isn't exhaustive. Indeed many of the early problems were posted at related workshops. We invite you to add further questions and update the wiki when progress is made on existing questions.

News

Jan 18, 2016: Open problems from the Sublinear Algorithms Workshop at the John Hopkins University have been posted.

May 09, 2015: The entire list is now available as a single pdf. Checking the online version is still recommended. The pdf may become outdated and we can't promise prompt updates.

May 07, 2015: The wiki has just been updated to MediaWiki 1.23, the current long term support release. Please notify us at admin@sublinear.info if anything stops working.
