Simple Algorithm for Simple Timed Games
2009
2009 16th International Symposium on Temporal Representation and Reasoning

We search to solve finite-horizon reachability games on Task TGA by building strategies in the form of Simple Temporal Networks with Uncertainty (STNU). ...
A practical consequence of this result is a fully forward algorithm for building STNU strategies. Potential applications of this work are planning and scheduling under temporal uncertainty. ...
The algorithm testing when an STNU is a winning strategy for a simple game is given on Figure 4 . ...
