摘要:
Partitioning large graph and hypergraph is often an important subproblem for complexity reduction or parallelization computing in mathematics and computer science. In general, most partitioning problems are NP-hard and even hard to approximate. With the advent of ever instances in various applications, such as VLSI cuicuit design and image processing,approximating graph and hypergraph partition problems become more and more important and challenging. In the talk, we will introduce our recent results on approximating graph and hypergraph partitioning problems with applications via (complex) semidefinite programming techinques.
