A Hamiltonian cycle is a Hamiltonian Path such that there is an edge (in graph) from the last vertex to the first vertex of the Hamiltonian Path. It is in an undirected graph is a path that visits each vertex of the graph exactly once.Functions and purposesBegin 1. function isSafe() is used to check for whether it is adjacent to the previously added vertex and already not added. 2. function hamiltonianCycle() solves the hamiltonian problem. 3. function hamCycle() uses hamiltonianCycle() to solve the hamiltonian problem. It returns false if there is no Hamiltonian Cycle ... Read More

In this Program we will basically find a feedback arc set which contains edges which when removed from the graph, graph becomes directed acyclic graph.AlgorithmBegin function checkCG(int n) : n: number of vertices. arr: struct graph variable. Initialize cnt = 0 and size = (n-1). For i =0 to n-1 if (cnt == size) return 0 if (arr[i].ptr == NULL) Increase cnt. for j = 0 to n-1 while (arr[j].ptr != NULL) if ((arr[j].ptr)->des == (arr[i].ptr)->des) ... Read More

In this program we need to find the Edge Connectivity of a Graph. An Edge Connectivity of a Graph of a graph means it is a bridge, removing it graph will be disconnected. Number of connected components increases with the removing of bridge in a disconnected undirected graph.Functions and pseudocodeBegin Function connections() is a recursive function to find out the connections: A) Mark the current node un visited. B) Initialize time and low value C) Go through all vertices adjacent to this D) Check if the subtree rooted with x has a connection to one ... Read More

In this program a random graph is generated for random vertices and edges. The time complexity of this program is O(v*e). Where v is the number of vertices and e is the number of edges.AlgorithmBegin Develop a function GenRandomGraphs(), with ‘e’ as the number of edges and ‘v’ as the number of vertexes, in the argument list. Assign random values to the number of vertex and edges of the graph, Using rand() function. Print the connections of each vertex, irrespective of the direction. Print “Isolated vertex” for the vertex having no ... Read More

The algebraic expression is a combination of numbers, variables (x or y), and arithmetic operators like +, -, *, and /. In this article, we'll write a C++ program to find the maximum value of an expression in the form (x1 + x2 + x3 + . . . + xa) * (y1 + y2 + . . . + yb) where a total of a+b integers are given. Our task is to split these integers into two groups, one with a numbers and the other with b numbers, and calculate the product of their sums. By ... Read More

This is a C++ program to perform Optimal Paranthesization using Dynamic Programming.AlgorithmBegin Take the length n and dimension of matrix as input. MatrixChain() to find out minimum multiplications: Arguments: a[i][j]=Minimum number of scalar multiplications needed to compute the matrix A[i]A[i+1]...A[j] = A[i..j] where dimension of A[i] is p[i-1] x p[i]. a[i][j] means cost is zero when multiplying one matrix. L is chain length. m = cost / scalar multiplications. Body of the function: for i = ... Read More
