Abstract

The ability ofreacting to changes in the external environment is ofcrucial importance within the context ofsof tware agents. Such feature must however be suitably reconciled with a more deliberative rational behaviour. In this paper we show how different behaviours of environment-aware agents can be naturally specified and computed in terms oflogic program updates. Logic program updates are specified, in our setting, by the language ofup dates LUPS. We show how such language can be used to model the more reactive behaviours, while keeping the more deliberative features provided by its underlying Dynamic Logic Programming paradigm. The obtained declarative semantics sets a firm basis for the development, implementation, and analysis of environmentaware agents.
