Define Deadlock with Resource request and allocation graph (RRAG)

Deadlocks can be described through a directed bipartite graph termed as a RRAG that is Resource Request Allocation graph. A graph G = (V,E) is termed as bipartite if V can be decomposed in two disjoint sets V1 and V2 therefore every edge in E joins a vertex in V1 to a vertex in V2. Assume that V1 be a set of processes and also V2 be a set of resources. Thus the graph is directed we will seems as:

  • An edge (Rj,Pi) that is an assignment edge to mean that resource Rj has been assigned to process Pi
  • An edge (Pi,Rj) (termed as a request edge) to implies that process Pi has requested resource Rj
