  • Based on PN search which is a best first search, a new search algorithm named PN# is proposed in this paper. Being easiest to (dis)prove, the node with least pn or dn is always expanded first in the naïve implementation of PN search. However, the frontier nodes can not be sorted by the initialized value of their pn and dn. Especially, the brother nodes is always expanded at the same degree though some of them are superior than others. For above reasons, the domain knowledge is introduced, which… CONTINUE READING
