Graph data sets are prevalent in various domains like social networks and biological networks. Label-Constrained Reachability (LCR) queries aim to determine if a vertex can reach another vertex through specific labeled edges. Existing works utilize exhaustive search or graph indexing techniques, but

The undecidability of the reachability analysis in rectangular hybrid automata (RHA) poses challenges for verifying cyber-physical systems. This complexity was demonstrated through a reduction from the Halting problem of two counter machines by Henzinger et al. Additionally, the review of computabil

Routing protocols in the network layer dictate how data packets are routed through a network. This lecture delves into key concepts such as reachability, routing protocol components, and the workings of Distance Vector (DV) algorithms. It explains how updates propagate in networks efficiently with D

Logic coverage in software testing involves deriving predicates from decision statements in programs. Programmers aim to keep predicates simple to ensure effective testing. Applying logic criteria to program source code can be challenging due to reachability and controllability issues. The provided

Logic coverage from source code involves deriving predicates from decision statements in programs, where most predicates have less than four clauses. Wise programmers aim to keep predicates simple, as they affect coverage criteria such as COC, ACC, ICC, and CC, which collapse to predicate coverage (
