Multiple authors of a paper

If more authors of the same paper attend the conference, the additional authors will register as non-presenting participants, with a discounted rate and having an option for late registration.

Authors with multiple papers

Only papers presented by a registered presenting author will be included in the conference program.

Each regular (full or short) paper of the same presenting author will require a full fee.

There is a limit of no more than three presentations for a presenting author, regardless of the paper category.
