The Non-Associative Lambek Calculus with Product in Polynomial Time
We prove, by introducing a new kind of sequent calculus, that the decision problem for the non-associative Lambek calculus with product belongs to PTIME. This solves an open prolem...

Reasoning About Actions: Steady Versus Stabilizing State Constraints
In formal approaches to commonsense reasoning about actions. the Ramification Problem denotes the problem of handling indirect effects which implicitly derive from so-called state...

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...

A Calculus for Link-Time Compilation
We present a module calculus for studying a simple model of link-time compilation. The calculus is stratified into a term calculus, a core module calculus, and a linking calculus. ...

Indirect and Conditional Sensing in the Event Calculus
Controlling the sensing of an environment by an agent has been accepted as necessary for effective operation within most practical domains. Usually, however, agents operate in par...
