Due to the coronavirus pandemic, an international conference on Group Decision and Negotiation 2020 was canceled.

Group Decision and Negotiation is an international conference organized yearly by the INFORMS section on Group Decision and Negotiation. In 2020, it was scheduled to be held on June 7th-11th in Toronto. Prof. Gregory Kersten, Ewa Roszkowska and Tomasz Wachowicz, the N.EA team members, are permanent members of the program committee of GDN conferences. The conference presentations are issued as Springer proceedings in the Lecture Notes on Business Information Processing series, and despite the conference cancellation, the submissions which passed the revision process will be published in LNBIP this year too.
