The next E-node is the one with the least cost. The cost function is useful for determining the next E-node. All children of a dead node have already been expanded.Įach node X in the search tree is associated with a cost. Dead node is a generated node that is not to be expanded or explored any further. In other words, an E-node is a node currently being expanded.ģ. E-node is a live node whose children are currently being explored. Live node is a node that has been generated but whose children have not yet been generated.Ģ. There are basically three types of nodes involved in Branch and Boundġ. It is similar to the backtracking technique but uses a BFS-like search. The search for an answer node can often be speeded by using an “intelligent” ranking function, also called an approximate cost function to avoid searching in sub-trees that do not contain an answer node. But no matter what the initial state is, the algorithm attempts the same sequence of moves like DFS. This always finds a goal state nearest to the root. We can perform a Breadth-first search on the state space tree. ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.
