In order to ensure that the reviewing effort is focused on the highest quality submissions, the reviewing process will be a two-step one. (1) The program chairs will filter out submissions deemed inappropriate, either due to writing, topics or content, and such papers will not receive reviews, only a rejection notice; all authors will be notified whether their paper passed or not this first filtering stage. (2) The papers will then be distributed to program committee members for a traditional and thorough reviewing process.

APPT 2021 utilizes a double-blind review process. The authors should not apprise any information about their names or institutions in the submitted paper. Besides authors' names and institutions, other hints of identity should also be removed from the submitted paper. The authors should also be careful when naming files mentioned in the paper, for example, file names like Joe.Smith.dvi should be removed.

It is also important for the authors to use care in referring to related work, especially their own. Citation of their own previous work is still required, as it is necessary for the reviewer to grasp the context. However, the authors must not use any terms like "my" or "our" to refer previous work. Instead, they should discuss their own past work in the third person. The authors should also cite anonymous work when necessary, meanwhile, they should also send the deanonymized reference to the PC chair in separate email.
