This is a java program to create a random linear extension of DAG. Linear extension of DAG is nothing but topological sorting in simple terms. Here is the source code of the Java Program to Create a Random Linear Extension for a DAG. The Java program is successfully compiled and run on a Windows system. … Read more
This is a java program to find the minimum spanning tree of a graph. Given a connected, undirected graph, a spanning tree of that graph is a subgraph that is a tree and connects all the vertices together. A single graph can have many different spanning trees. We can also assign a weight to each … Read more
This is a java program to find shortest path from a single vertex. The Bellman–Ford algorithm is an algorithm that computes shortest paths from a single source vertex to all of the other vertices in a weighted digraph.[1] It is slower than Dijkstra’s algorithm for the same problem, but more versatile, as it is capable … Read more
This is a java program to find shortest path between all vertices using FLoyd-Warshall’s algorithm. In computer science, the Floyd–Warshall algorithm (also known as Floyd’s algorithm, Roy–Warshall algorithm, Roy–Floyd algorithm, or the WFI algorithm) is a graph analysis algorithm for finding shortest paths in a weighted graph with positive or negative edge weights (but with … Read more
This is a java program to solve a matching problem for stable marriage matching problem. In mathematics, economics, and computer science, the stable marriage problem (SMP) is the problem of finding a stable matching between two sets of elements given a set of preferences for each element. A matching is a mapping from the elements … Read more
This is a java program to implement Hungarian Algorithm for Bipartite Matching. The Hungarian method is a combinatorial optimization algorithm that solves the assignment problem in polynomial time and which anticipated later primal-dual methods. Here is the source code of the Java Program to Implement the Hungarian Algorithm for Bipartite Matching. The Java program is … Read more
This is a java program to implement Edmond’s Algorithm for maximum cardinality matching. In graph theory, a branch of mathematics, Edmonds’ algorithm or Chu–Liu/Edmonds’ algorithm is an algorithm for finding a maximum or minimum optimum branchings. This is similar to the minimum spanning tree problem which concerns undirected graphs. However, when nodes are connected by … Read more
This is a java program to check whether graph contains Eulerian Cycle. The criteran Euler suggested, 1. If graph has no odd degree vertex, there is at least one Eulerian Circuit. 2. If graph as two vertices with odd degree, there is no Eulerian Circuit but at least one Eulerian Path. 3. If graph has … Read more
