- link(a,b). link(a,c). link(b,c). link(b,d). link(c,d). link(d,e). link(d,f). link(e,f). link(f,g). Using the above Formulate the appropriate Prolog predicate "path(X,Y,N)" which is true if (and only if) there is a path of length "N" from node "X" to node "Y". For example, there is a path of lengthGiven: P={a, b, c, d, e, f, g, h, i} and Q={a, e, o, i, u, } List the elements of the sets: A. PnQ 2.PUQlink(a,b). link(a,c). link(b,c). link(b,d). link(c,d). link(d,e). link(d,f). link(e,f). link(f,g). Using The above Formulate the appropriate Prolog predicate "path(X,Y,N)" which is true if (and only if) there is a path of length "N" from node "X" to node "Y". For example, there is a path of length 2 from "a" to "d": "a->b->d", but also "a->c->d", and so "path(a,d,2)" gives "true" (two times). There is also a path of length 3 from "a" to "d": "a->b->c->d". Test this predicate out on the above network to verify whether or not it is working correctly. Once this is working correctly, note now, that e.g., "path(a,e,N)." will give multiple answers:
- how would I program in c++ language ... a program that takes in graph data from a CSV file , works with any 2d graph, and is able to solve this graph using a dynamic array , think of this as a manhattan graph where its able to give me an optimal path and score with the values from the CSV valuesA tile of a monkey puzzle has four monkey halves that can be labelled as north(N), east (E), south (S), and west (W) half. In addition to the shape of the borderrectangle, these halves determine which edges can be placed next one other. There isalso another way to define how the tiles can be placed: Each tile corner (i.e. compassdirections NE, SE, SW, and NW) has a monkey quarter. If we abstract this quarter, forexample, with a letter, only the tiles with the same letter in their touching corners canbe adjacent. illustrates one valid solution for this quarter monkey puzzle.Are the two monkey puzzle representations equivalent in the sense that if we have apile of ‘half monkey’ tiles H, it is possible to define a pile of ‘quarter monkey’ tilesQ that gives exactly the same set of solutions for the puzzle (and vice versa)?Write a java program that takes a matrix representing an undirected graph (connectivity matrix) and finds the minimum spanning tree (using kruskal's or prim's algo.) of that graph and then print it graphically ( Graphical user interface should be used)
- Display the resulting graphs of the following set operations, and state if any of the results are isomorphically identical to any of the other results. (1.1) 4 - 1 (1.2) 2 ∩ 4 (1.3) (2 U 3) - 1Data Structures and Algorithm(C Programmming) You are given a weighted undirected graph G = (V,E), where E and V denote set of edges and vertices, and a minimum spanning tree T of that graph G. Answer the following questions about G and T on minimum spanning trees. (a) Suppose we decrease the weight of one of the edges in G that is not among the edges in T. Suggest an algorithm in plain English that determines whether T is still a minimum spanning tree, and if it is not, calculates a minimum spanning tree of G. Explain the running time of your algorithm. (Note: Your algorithm should be faster than Prim’s and Kruskal’s) (b) Consider the following algorithm running on G = (V,E). Would it calculate a valid MST of G? If yes, explain your reasoning in plain English, if no, provide a counter example graph that the algorithm will fail producing an MST. Also, what is the running time of the algorithm in the previous question. Show your analysis.The function f is defined for non-negative integers a and b recursively as follows:f(a, b) ={0 if a = 0 or b = 0f(a − 1, b − 1) + 2a − 1 if a = bf(a − b, b) + f(b, b) if a > bf(a, a) + f(b − a, a) if a < b}Compute f (3, 2) by drawing a recursion tree showing all of the computationrequired and then use your tree to compute the answer.

Recurrence Relation, ci = in centre of each upright equilateral triangle in ci-1, draw an upside down equilateral triangle ? such that its corners touch the edges of the upright one. Draw the first 4 iterations, starting with c0. You may want to draw c3 large. Each should be a separate drawing.Get your work checked by an IA/TA/Instructor. Count the total # of triangles for each iteration in a).Note: Triangles can be of any orientation.Only count the individual triangles. Do not count a triangle which has triangles inside it. Determine T(0), the # of triangles in the 0th term. Determine the recurrence relation, T(n), that gives the # of triangles in the nth term, for n ≥ 1.For the traversal log: {X, Y, Z, W, Y, A, B, C, D, Y, C, D, E, F, D, E, X, Y, A, B, M, N}, a.
