Hello! I want to learn disjoint set structure and how to optimize Kruskal's algorithm. I tried to find good tutorial, but I did not find it. I will be happy if you help me. disjoint-set,kruskal,graphs -1 RHandarov 7 years ago ...
Using Disjoint Set DS for solving the problem RunMAKE−SET(u)MAKE−SET(u)for each of the V nodes in the graph. RunUNION(u,v)UNION(u,v)for each edge(u,v)(u,v)in the graph. For each Query (u,v):a)IfFIND(u)==FIND(v)FIND(u)==FIND(v)then answer = trueb)Else answer =...

A New Algorithm for Maintaining Arc Consistency After Constraint Retraction Summary: Dynamic Constraint Satisfaction Problems play a very important role in modeling and solving real-life problems where the set of constraints is changing. The paper addresses a problem of maintaining arc consistency after ...
