anyone can give me useful link which contains recursive best first search algorithm pseudo code?
like this (for IDDFS)
thanks for your help

Why do you need a recursive realization of BFS? It seems there is no way to use the recursion stack for performing it: you need a queue as in classical BFS or you have to visits vertices several times as in IDDFS anyway.
do you know what is RBFS?
I didn't say recursive BFS, I said RBFS (Recursive Best First Search) which is heuristic based algorithm
anyway thanks for your unrelated answer, I found one link
In addition to Grevozin's answer, this may provide related info.
