General Considerations for Research -artificial intelligence:

If we can specify the initial state, the operators or a consumer and the goal check for a search problem, that already we knew where to start, how to move and when to stop in our search and why. This put up the important discussion of how to choose which operator or a consumer apply to which state at any stage during the search. We will have to make call an answer to this question of discussion, a search strategy. Before we get think about accurately what strategy can be use, as the following need to be taken into consideration:   

• Path or Artifact

Broadly speaking, actually there are two different reasons to undertake a research after searching: to find an artifact(a particular state), or we can say find a path from atlest one given state to another given state. Whenever you're searching for an exactly path or an artifact will affect many aspects of your agent's search just like in your way, including its goal test, what it records along the way and the search strategies and analysis available to you needed for using purpose. 

For example, in the maze below, the game involves finding a route from the upper left hand corner to the bottom right hand corner. We all knew what the exit looks like (a gap in the outer wall), so that's why we do not search for an artifact. Rather, the point of the searching then researching is to find a path, so that the agent might remember where it has been.
