NMR is the premier forum for results in the area of nonmonotonic reasoning. Its aim is to bring together active researchers in this broad field within knowledge representation and reasoning (KRR), including belief revision, uncertain reasoning, reasoning about actions, planning, logic programming, preferences, deontic reasoning, argumentation, causality, and many other related topics including systems and applications. NMR has a long history - it started in 1984 and has been held every two years until 2020, and then every year. Recent previous NMR workshops were held in Hanoi (virtually) (2021), Rhodes (virtually) (2020), Tempe (2018), Cape Town (2016), Vienna (2014), Rome (2012), Toronto (2010), and Sydney (2008).
