Method of communication between connected components in a non-directed graph cyclesA bus arbitration scheme is implemented in a system where an arbitrary assembly of nodes on a system bus have been resolved into an acyclic directed graph. The hierarchical arrangement of nodes has one node designated...

to find the components. The problem is also known as interconnect diagnosis of wiring networks in VLSI. The graph hasnvertices andkcomponents, butkis not part of the input. We present a deterministic algorithm usingO(min{k,logn}) queries and a randomized algorithm using expectedO(min{k, log...
