Generic Search Methods

  • Generic Search Methods are GPS for which every problem can be expressed as search

  • One particular example of a Generic Search Method is the A* algorithm.

  • A* works for problems that can be represented as a state space i.e. a graph of states. Initial conditions of the problem are represented as start state , goal conditions are represented as end state

  • A* is an informed search or heuristic search approach that uses the estimation function:

    • f(n)=g(n)+h(n)

    • g(n) the cost to get from the star state to current state n

    • h(n) estimated cost to get from current state n to end state

    • f(n) estimated total cost from start state through current state n to the end state
