Explain Resource request and allocation graph (RRAG)
Deadlocks can be explained by a directed bipartite graph known as a Resource-Request-Allocation graph (RRAG).A graph G = (V,E) is known as bipartite if V can be decomposed into two disjoint sets V1 and V2 such that every edge in E joins a vertex in V1 to a vertex in V2. Suppose V1 be a set of processes and V2 be a set of resources. As the graph is directed we will consider:
a) An edge (Rj,Pi) that is an assignment edge to mean that resource Rj has been allocated to process Pi
b) An edge (Pi,Rj) that is called a request edge to mean that process Pi has requested resource Rj
