Domain Transition Graph

For instance the domain transition graph is an automaton for representing the possible values of planning state variables chen huang zhang 2008.

Domain transition graph. Definition 1 domain transition graph dtg given a state variable x x defined over dx its dtg gx is a directed graph with vertex set dx and arc set ax. Eduabstractrecent advances in classical planning have used the sas formalism and several effective heuristics have been devel oped based on the sas formalism. Thedomain transition graph dtg of v is the labeled directed graph dtg v withvertices d v and an arc d d0 labeled with action a 2a whenever either i pre a.

Introduction causal graphs dtgs example results conclusionreferences domain transition graphs de nition domain transition graph. However the graph based view of the mdp is particularly suited for representation learning 7. We use tv v0 to.

We use tv v to. A direc tional arc v v belongs to ax if and only if there is an action o with v del o and v add o in which case we say that there is a transition from v to v. Toropila and barták 2010 also used.

Let v a c i g be an fdr planning task and let v 2v. Louisst louis mo 63130 usa rh11 chen zhang cse. Transition graph is just an other way of representing the domain s dynamics.
