In the past few decades, there has been a large amount of work on algorithms for linear network flow problems, special classes
of network problems such as assignment problems (linear and quadratic), Steiner tree problem, topology network design and
nonconvex cost network flow problems.Network optimization problems find numerous applications in transportation, in communication
network design, in production and inventory planning, in facilities location and allocation, and in VLSI design.The purpose
of this book is to cover a spectrum of recent developments in network optimization problems, from linear networks to general
nonconvex network flow problems.
