NMR is the premier forum for results in the area of Non-Monotonic Reasoning. Its aim is to bring together active researchers in this broad field within knowledge representation and reasoning (KR), including belief revision, uncertain reasoning, reasoning about actions, planning, logic programming, preferences, argumentation, causality, and many other related topics including systems and applications. See the NMR webpage.

NMR has a long history - it started in 1984 and, up until last year, was held every two years. Recent previous NMR workshops were held in Rhodes (virtually) (2020), Tempe (2018), Cape Town (2016), Vienna (2014), Rome (2012), Toronto (2010), and Sydney (2008).

The NMR workshop series is the premier specialised forum for researcher in non-monotonic reasoning and related areas. This will be the 19th workshop in this series. Its aim is to bring together active researchers in the broad area of non-monotonic reasoning, including belief revision, reasoning about actions, argumentation, declarative programming, preferences, non-monotonic reasoning for ontologies, uncertainty, and other related topics.

NMR 2021 is co-located with KR 2021.
