Among the most successful ordering heuristics are heuristics which enforce a fail first strategy by using the min-domain property ... WebPlanning as a CSP: Overview • We need to “unroll the plan” for a fixed number of steps: this is called the horizon • To do this with a horizon of k: • construct a CSP variable for each STRIPS variable (eg. A,B,C) at each time step from 0 to k • construct a boolean CSP variable for each STRIPS action (eg. a1, a2) at each time step citrix file for windows
