Not sure about what's wrong with your code is but the answer to the problem is Warshall's algorithm for graph closure. Just to brief, say we are given the adjacency matrix A[1] where A[1][i] [j] = 1 if there's an edge from i to j. Let A[k][i][j] be the the number of paths from i to j passing

Here's the code. void Closure(int **a, int v) //a is the given adjacency matrix and v is the number of vertices { int **t1 = new int*[v]; int **t2 = new int*[v]; for(int i = 0; i v; ++i) { t1[i] = new int[v]; t2[i] = new int[v];

Consider a rectangle of M N .Inside that there are many small overlapping rectangles.Now i have to minimize overlapping area such that the % increase in size (M N) - 0 . means readjust smaller rectangles such that they do't overlap. Please suggest some algorithm !

Can it be a solution? At first let us think all the edges are undirected. That is if a adjacent to b then both a-b and b-a are present. then we discard a-b if a is the current vertex with maximum outdegree and b is its adjacent with minimum outdegree and b-a is present we continue it again and
