QUESTION
I am trying to solve 8puzzle problem and for that, I need neighboring elements of the current state.
Current state(or data) looks like this - a 2D array with 0 representing blank state.

QUESTION
In Artificial intelligence, these algprithms are very popular. I tried looking for methods to solve the 8puzzle problem and it seems like both of them have a similar approach. Can anyone explain what is the difference?
...ANSWER
Answered 2018-Oct-28 at 19:02Algorithms like weighted A* (Pohl 1970) systematically explore the search space in ’best’ first order. ’Best’ is defined by a node ranking function which typically considers the cost of arriving at a node, g, as well as the estimated cost of reaching a goal from a node, h. Some algorithms, such as A∗ ǫ (Pearl and Kim 1982) also consider the distance of a node from the goal, d. Hill-climbing algorithms are less deliberative; rather than considering all open nodes, they expand the most promising descendant of the most recently expanded node until they encounter a solution.

Is this Hamming and Manhattan priorities computation from the above link correct?
...For example, the Hamming and Manhattan priorities of the initial search node below are 5 and 10, respectively.
Note that we do not count the blank square when computing the Hamming or Manhattan priorities.
ANSWER
Answered 2018-Jan-11 at 10:47So, 3 of them are in the places and 5 not in the right places. This gives as 5 as Hamming distance, and some small manipulations needed to see that Manhattan priority is 10.
