WebLeast constrained value It is a value-level ordering heuristic that assigns the next value that yields the highest number of consistent values of neighboring variables. Intuitively, this procedure chooses first the values that are most likely to work. Remark: in practice, this heuristic is useful when all factors are constraints. 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

Our heuristic CSP method was distilled from an analysis of the network, and has the virtue of being extremely simple. It can be implemented very efficiently within a symbolic CSP framework, and combined with various search strate- gies. This paper includes empirical studies showing
