Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time. This means that the increasing complexity of the graphs increased the algorithm's running time ...

Most problems can be solved by many different algorithms, each with its own demands on time and space. Complexity theorists sort problems into categories, called complexity classes, based on the ...

Graph algorithms and processing form the backbone of numerous applications across science and industry, ranging from social network analysis to large-scale data management.

Graph algorithms and sparsification techniques have emerged as pivotal tools in the analysis and optimisation of complex networked systems. These approaches focus on reducing the number of edges ...

One of the first algorithms for this is Jarník’s algorithm, by Czech mathematician Vojtěch Jarník in 1930. Later this was rediscovered by Robert C. Prim in 1957 and in 1956 by Edsger W ...

This podcast from the Department of Energy’s Exascale Computing Project (ECP) examines the ExaGraph Project, an ECP co-design center, tasked with developing efficient implementation of graph ...

Built on a temporal graph model that captures the ever-changing nature of satellite networks, the two methods offer complementary approaches for scheduling tasks.
