Properties of Breadth First Search algorithm

Performs non-directed (possibly exhaustive) search of the graphin a breadth-wise manner, until the goal node (state) is reached.

Can be treated as a general framework, for which there arespecific (refined) cases algorithms: Best First Search, A,algorytm Dijkstry, and other.

Breadth First Search operates on two sets: Open (contains nodesstill to be considered / visited) and Closed (contains nodes alreadyvisited).

Every node is equipped with possibility to remember a referenceto its ancestor (parent), so that when the search solution is found,it is possible to backtrack the path.



Breadth First Search

Algorithm

1 Set empty reference to parent for the initial node, and add thisnode to Open set.

2 While Open remains non-empty, repeat:

1 Take (and remove) one node from Open set. Let us denote itas v.

2 If v is the solution-node (it satisfies the stop condition) thenstop the algorithm and return v as the result.

3 Insert into Open set all descendants (children) of v , such thatdo not exist in Closed set. In all these descendants, memorizereference to v as their ancestor.

4 Insert v into Closed set.



Breadth First Search

Path backtracking

1 Assign the solution node to a temporary node named v.

2 Initialize a sequence (representing the path) with v: Path = (v).

3 While v has a non-empty ancestor repeat:

1 Assign to v its ancestor (v v.parent).2 Prepend the path Path with v.



Exemplary execution (graph from page 3)

1 Open = {v1}, Closed = {}.

2 Open = {v1} , so the loop body is executed:2.1 v = v1 , Open = {}.2.2 v = v1 , v8 (stop condition not satisified).2.3 Open = {v2 , v3 , v6}.

2.4 Closed = {v1}.

2 Open = {v2, v3, v6} , so the loop body isexecuted:

2.1 v = v2 , Open = {v3 , v6}.2.2 v = v2 , v8 (stop condition not satisfied).2.3 Open = {v3 , v6} (attention: v3 as a child of v2 is not

added to Open for the second time).

2.4 Closed = {v1 , v2}.

2 Open = {v3, v6} , so the loop body is executed:2.1 v = v3 , Open = {v6}.2.2 v = v3 , v8 (stop condition not satisfied).2.3 Open = {v6 , v4} (attention: v1 as a child of v3 is not

added to Open, since it exists in Closed.)

2.4 Closed = {v1 , v2 , v3}.

Remarks on Breadth First Search

Sets Open and Closed in the case of Breadth First Search aretypically implemented as regular FIFO queues. Only inspecialized versions of the algorithm i.e. in BestFirstSearch or A,these sets are implemented respectively as: a priority queue and ahash map.

If the search is related to a tree (graph with no cycles), then theClosed can be omitted.

Breadth First Search is not in anyways directed for a fast arrival tothe goal (it traverses the graph breadth-wise): it does notminimize the path, it does not use any heuristic.

Best-First-Search algorithm

Properties of Best First Search (Judea Pearl)

Every state (node) v is given a heuristic score f (v) , which estimates how far this state isfrom the goal state.

The algorithm searches through states in the increasing order of heuristic function.

The Open set is implemented as a priority queue which sorts the states according to theheuristic function. Insertion of a new element to the queue is of complexity: O(log n).Polling (taking with removal) the minimal element from the queue is of complexity:O(log n).

The Closed set is implemented as a hash map. Checking if a stat has already been visited(exists in the Closed set) is of complexity: O(1).

Every state keeps a reference to its most favorable ancestor (known so far).



Best First Search

Algorithm

1 Set empty reference to the parent for the initial state and add this stateto Open set.

2 While Open remains non-empty, repeat:

1 Take (and remove) on state v from Open (it is the best state in the sense of appliedheuristic function).

2 If v is the goal state (it satisfies the stop condition) then stop the algorithm andreturn v as the result.

3 Generate all descendant states (children) of v and for each of them perform:

1 If the child is in Closed then do not investigate it further (continue).2 Calculate the heuristic score for the child.3 If the child does not exist in Open then add it and set up v as its ancestor

(parent).4 If the child exists in Open and its newly calculated heuristic score is better

than the previous one, then: replace this score, replace the reference toparent, and reposition the child within Open set.




Sudoku

Sudoku 9 9Given an initial state of a 9 9 board, divided additionally into 9 subsquaresof size 3 3 each, the goal is to fill the whole board in such a way that inevery row, every column and every subsquare all numbers from {1, 2, . . . , 9}are used.

General n2 sudoku

Given an initial state of a n2 n2 board, divided additionally into n2subsquares of size n n each, the goal is to fill the whole board in such a waythat in every row, every column and every subsquare all numbers from{1, 2, . . . ,n2} are used.

Exemplary heuristics

Sudoku (naive heuristic)

We start from initial board (initial state) and successively put alladmissible numbers into empty squares (max. 9 children per treelevel). We say that a state is the closer to the solution the fewer emptysquares it contains.

f (v) =

, if state v is contradictory;number of empty squares in v.



Exemplary simple heuristics

Sudoku (heuristic according to the minimum of remaining possiblities)

Identify v with sudoku board. Let Rv(i, j) denote remaining possibilities for thesquare (i, j) of board v i.e. possibilities remaining by eliminating numbersexisting in i-th, row and j-th column and in the subsquare to which (i, j)belongs.

We say that a state is the closer to the solution, the fewer remainingpossibilities it has for some subsquare. Children states ought to be fastenedunder this very subsquare.

f (v) = mini,j

#Rv(i, j).




Sudoku (heuristic according to the sum of remaining possiblities)

We say that a state is the closer to the solution, the smaller is the sum of theremaining possibilities cardinalities taken over all empty subsquares.Children states ought to be fastened under: arg mini,j #Rv(i, j).

f (v) =

i,j

#Rv(i, j).




n-queens (naive heuristic)

We start from the empty chess chessboard and we add queens into successiverows.

We say that a state is the closer to the solution the fewer empty rows it has.

f (v) =

, if some queens attack each other;number of empty rows in v.




n-queens (heuristic according to the maximum of remaining possibilities)

Let Rv denote the number of remaining non-attacked squares in v. We saythat a state is the closer to the solution, the more non-attacked squares it has.

f (v) =

, if some queens attack each other;Rv.



Minimal sudoku

Problem (in generality for n2 sudoku)

The task is to find all initial sudoku states, such that there exist a uniquesolution for each of them and that the number of given initial numbers is thesmallest.

Proof that such states exist

Starting from any solved sudoku board (completely filled) removesuccessively numbers from it, and after each removal check if new sudokucan be solved uniquely. Stop when more than one solution exists. Knowingthat a completely empty sudoku board is non uniquely solvable, it is easy tosee that the above procedure must have some stopping moment at a partialfilling of the board.



Searching for minimal sudokus

Sketch of a greedy algorithm

Start from some solved (completely filled) sudoku board.

Let the descendants (children) of given state be all states created by theremoval of one number from it. Thus, n4 children are possible for thefilled board (then n4 1,n4 2, . . .).For every child we check (via Best First Search algorithm for a regularsudoku problem), if there exist at least 2 solutions.

If a certain state has a unique solution, but all its children have morethan one solution, then this state should be memorized as a candidatefor being a minimal sudoku.

The algorithm must be carried out until the whole graph is searchedthrough. One must not stop after the first candidate is reached, since inother graph regions there might exist other candidates with fewerinitial numbers.



Searching for minimal sudokus

For n = 2 starting from the board beneath, 128 minimal sudokus have been found (with 4 initialnumbers).

Obviously, in order to know the true number of all base (or template) solutions one wouldhave to: (1) identify all the symmetric distributions, (2) identify all states equivalent due topermutation of symbols, (3) trigger the search procedure only for non-equivalent initial states.



Uwagi koncowe o Best First Search

Best First Search searches by usually moving depth-wise in thegraph (but not identically as Depth-First-Search), andsuccessively departing further away from the initial state.

When reaching an illegal state (in particular, when all itsdescendants are illegal), the algorithm retreats to states of worseheuristic value (but still best known value so far).

The number of such retreats depends on: the quality of usedheuristic and the manner in which descendants are generated(any problem-specific knowledge can be helpful here to improvethe search; at least not to allow directly illegal descendants).

A algorithm

Properties of A algorithm

(Hart, Nilsson, Raphael, 1968)

The ordering function for the Open set is the following sum:

f (v) = g(v) + h(v),

where g(v) is the true cost (distance) paid for the path from the initialstate up to state v, whereas h(v) is a heuristic estimating the cost(distance) from v to the goal state.

Function h has to be the (so-called) admissible heuristic, i.e. it must notoverestimate the cost (distance) to the goal state (more about it later. . . ).

In applications like: path-finding or routing (where a physical orgeographical graph is considered) a frequent and correct choice for h isa common distance over a straight line from v to the goal (we do notoverestimate for certain).


A algorithm

Properties of A algorithm

(Hart, Nilsson, Raphael, 1968)

Contrarily to Best First Search, A takes into account also g(v), notonly the goal-oriented heuristic. Therefore, in the path (beingbuilt) from one side one prefers states which are close to theinitial state and from the other side (simultaneously) one prefersstates close to the goal state (so that the sum is minimized).

Within the algorithm, each state v must be allowed to memorizeall is three costs: g(v), h(v), f (v).

By moving from ceratin v state to a w state, the value of g functionis calculated as: g(w) = g(v) + d(v,w), where d(v,w) denotes thetransition cost from v to w.

A

Algorithm

1 For the initial state, calculate its h, and set: g = 0, f = 0 + h. Then, set anempty reference to its ancestor (parent) and add the initial state to Openset.

2 While Open remains non-empty, repat:

1 Take (and remove) one state v from Open set (is is the best state with respect to f ).2 If v is the goal state (is satisfies the stop condition) then stop the algorithm and

return v as the result.

3 Generate all states w being children (descendants) of v and for each of them repeat:

1 If w exists in Closed set then do not investigate it further (continue).2 Calculate: g(w) = g(v) + d(v,w) and f (w) = g(w) + h(w).3 If w does not exist in Open then add it there, and set up v as its ancestor

(parent).4 If w exists in Open and newly calculated f for it is better, then update its g, f

(and reference to parent), and update its position within Open set.
