I'm new to Prolog and currently implementing DFS (depth-first search) and BFS (breadth-first search) algorithms. My DFS works fine as the code below, but the BFS is terminated and aborted when it reaches the leaf node (it doesn't backtrack and continue searching). I also read some sample code about this but there are some functions they don't.

I'm studying search strategies in the state space in Prolog, I'm looking at the following program, is the famous water jugs problem, to keep it simple you have 2 jugs (4 and 3 litres), you can fill, empty and transfer the water into the other jug until the first is empty or the second is full. The goal is to have 2 litres (the jugs don't have any measuring). This implementation should be a.
In this tutorial, we are going to focus on Breadth First Search technique. In this technique, we first visit the vertex and then visit all the vertices adjacent to the starting vertex i.e., 0. Next, we pick the adjacent vertices one after another and visit their adjacent vertices and this process goes on and on until we reach the last vertex.
This Python tutorial helps you to understand what is the Breadth First Search algorithm and how Python implements BFS. Algorithm for BFS. BFS is one of the traversing algorithm used in graphs. This algorithm is implemented using a queue data structure. In this algorithm, the main focus is on the vertices of the graph. Select a starting node or.

Best First Search. Search in PROLOG Three types of search can be implemented in PROLOG using the same basic algorithm. The differences come in the choice of data structure used to implement the open and closed lists: Search Open List Closed List; Depth First: Stack: Set: Breadth First: Queue: Set: Best First: Priority Queue: Set: Setting up the Search. The main predicate for all three types of.
Implementing breadth-first search We can write code for problem-independent breadth-first search, to load as an alternative to the depth-first problem-independent code. Recall from the last chapter that breadth-first search finds states level-by-level (that is, by distance in number of branches from the starting state). To do this, it must keep facts about all states found but whose successors.
Breadth-first search (BFS) is an algorithm for traversing or searching tree or graph data structures. It starts at the tree root (or some arbitrary node of a graph, sometimes referred to as a 'search key'), and explores all of the neighbor nodes at the present depth prior to moving on to the nodes at the next depth level. It uses the opposite strategy as depth-first search, which instead.
In the missionaries and cannibals example, the state space is explored in an order determined by Prolog. In some situations, it might be necessary to alter that order of search in order to make search more efficient. To see what this might mean, here are two alternative methods of searching a tree. Depth first search begins by diving down as quickly as possible to the leaf nodes of the tree.
BFS (breadth first search) graph traversal (Python recipe). I think you should use collections.deque rather than writing your own queue class. Plus, a search algorithm should not visit nodes more than once. I think the Pythonic way of implementing visits should be a generator. To give accessing methods enough information to do useful things, every time I visit a node I return its parent.
Prolog programs are sequences of prolog terms, so prolog programs easily serve as input data. A prolog meta-interpreter uses program data as a basis for additional computations. In this section, several prolog meta-interpreters are discussed that modify the computation of prolog goals. Chapter 6 studies some prolog meta-interpreters for logic. Simple Prolog meta-interpreter. The following.

As in the example given above, BFS algorithm traverses from A to B to E to F first then to C and G lastly to D. It employs the following rules.
