Additive Fluents
We propose a situation calculus formalization of action domains that include numeric-valued fluents (so-called additive or measure fluents) and concurrency. Our approach allows fo...

Describing Additive Fluents in Action Language C+
An additive fluent is a fluent with numerical values such that the effect of several concurrently executed actions on it can be computed by adding the effects of the individual ac...

Using the Context-enhanced Additive Heuristic for Temporal and Numeric Planning
Planning systems for real-world applications need the ability to handle concurrency and numeric fluents. Nevertheless, the predominant approach to cope with concurrency followed b...

Tackling the Qualification Problem using Fluent Dependency Constraints: Preliminary Report
The use of causal rules or fluent dependency constraints has proven to provide a versatile means of dealing with the ramification problem. In this paper we show how fluent depende...

Computational Complexity of Planning with Temporal Goals
In the last decade, there has been several studies on the computational complexity of planning. These studies normally assume that the goal of planning is to make a certain fluent...
