Define Hill Climbing search.

1 Answer

Answer :

It is a loop that continually moves in a increasing value direction (i.e.) up hill and terminates when it reaches a “peak” where no neighbor has a higher value.

Description : Define A* search.

Last Answer : A* search evaluates nodes by combining g(n), the cost to reach the node and h(n), the cost to get from the node to the goal. f(n) = g(n) + h(n)

Description : Define Greedy Best First Search.

Last Answer : It expands the node that is closest to the goal (i.e.) to reach solution in a quicker way. It is done by using the heuristic function: f(n) = h(n).

Description : What energy does a train have climbing up a hill at a steady speed?

Last Answer : The train is expending mechanical energy to be lifted higher in the earth's gravity well. As it is lifted higher, it is collecting and storing potential energy because of the fact that it is in that gravity well.
