Modal Event Calculus
We consider a hierarchy of modal event calculi to represent and reason about partially ordered events. These calculi are based on the model of time and change of Kowalski and Sergo...

A Tool for Satisfiability-Based Commonsense Reasoning in the Event Calculus
We present a tool for commonsense reasoning in the classical logic event calculus using satisfiability. We describe the tool, which takes event calculus reasoning problems as inpu...

Variants of the Event Calculus
Abstract. The Event Calculus is a narrative based formalism for reasoning about actions and change originally proposed in logic programming form by Kowalski and Sergot. In this pap...

Representing Continuous Change in the Event Calculus
The Event Calculus of Kowalski and Sergot only deals with discrete change. This paper introduces a simplified version of the Event Calculus and extends it to deal with continuous ...

Hypothetical Reasoning from Situation Calculus to Event Calculus
Pinto and Reiter have argued that the Situation Calculus, improved with time handling axioms, subsumes the features of linear time temporal formalisms such as Event Calculus and I...

Event Calculus Planning Revisited
In 1969 Cordell Green presented his seminal description of planning as theorem proving with the situation calculus. The most pleasing feature of Green's account was the negli...

Modal Event Calculi with Preconditions
Kowalski and Sergot’s Event Calculus (EC) is a simple temporal formalism that, given a set of event occurrences, allows the derivation of the maximal validity intervals (MVIs) o...
