Termination: the computation is guaranteed to terminate, no matter how large the search space is. Completeness: an algorithm is complete if it terminates with a solution when one exists. Admissibility: an algorithm is admissible if it is guaranteed to return an optimal solution whenever a solution exists.

Heuristics for State-Space Search: It turns out that neither forward nor backward search is efficient without a good heuristic function. Let us recall that in a search technique a heuristic function estimates the distance from a state to the goal.
The Search Method. Search is a commonly used method in Artificial Intelligence for solving problems of this kind. The search technique explores the possible moves that one can make in a space of ‘states’, called the search space.

Search Algorithms in AI . Search techniques are general problem-solving methods. When there is a formulated search problem, a set of states, a set of operators, an initial state, and a goal criterion we can use search techniques to solve the problem (Pearl & Korf, 1987).
Artificial Intelligence State Space Search – Introduction State space search is a process used in the field of computer science, including artificial intelligence (AI), in which successive configurations or states of an instance are considered, with the goal of finding a goal state with a desired property.
Search is a central topic in Artificial Intelligence. This part of the course will show why search is such an important topic, present a general approach to representing problems to do with search, introduce several search algorithms, and demonstrate how to implement these algorithms in Prolog. • Motivation: Applications and Toy Examples • The State-Space Representation • Uninformed
Consider the explicit state space graph shown in the figure. One may list all possible paths, eliminating cycles from the paths, and we would get the complete search tree from a state space graph.
You have to fill the jugs with water .How can you get exactly 2 gallons of water in to 4gallons.Here the state space can defined as set of ordered pairs integers(x,y),such that x=0,1,2,3 or 4 and y=0,1,2 or 3;X represents the number of gallons in 4galoon jug and y represents quantity of water in the 3-gallon jug.
The space utilization of breadth first, measured in terms of the size of the open list, is B n where B is the branching factor– the average number of descendants per state — and n is the level. Depth first is NOT guaranteed to find the shortest path but it gets deeply into the search space.

The formalization of graph theory also afforded the possibility of state space search, a major conceptual tool of artificial intelligence. We can use graphs to model the deeper structure of a problem. The nodes of a state space graph represent possible stages of a problem solution; the arcs of the graph represent inferences, moves in a game, or other steps in a problem solution. Solving the
