WebJun 28, 2024 · In prolog, logic is expressed as relations (called as Facts and Rules). Core heart of prolog lies at the logic being applied. Formulation or Computation is carried out by running a query over these relations.

WebNov 12, 2024 · Okay, so I have the graph: and I want to be able to create a rule to find all the paths from X to Y and their lengths (number of edges). For example, another path from a to e exists via d, f, and g. Its length is 4. So far my code looks like this: edge (a,b). edge (b,e). edge (a,c). edge (c,d). edge (e,d). edge (d,f). edge (d,g). path (X, Y ... WebMay 30, 2024 · The graph in my implementation will be represented as a dictionary, where every key is a vertex, and the corresponding value is a list of all its neighboring vertices. Now, I have a few problems: I need to be storing the "parent" of each vertex in a data structure, so that it can be used for cycle detection. I am not sure about how to do that.
WebNov 23, 2024 · Here is the graph in a visual form with the root ( a) at the top. a Level 0 / \ b c Level 1 / \ / \ g f r e Level 2 Notice that the shortest path from a to g is a, b, g and not a, b, c, g as you expect. Even though c is connected to a, it is not on the path from a to g and so is not part of the solution.
