A network realization problem involves a given specification for some network parameters (such as vertex degrees or inter-vertex distances), and requires constructing a network G that satisfies, if possible. In many settings, it may be difficult or impossible to come up with a precise realization (e.g., the specification data might be inaccurate, or the reconstruction problem might be computationally infeasible). In this expository paper, we review various alternative approaches for coping with these difficulties by relaxing the requirements, discuss the resulting problems and illustrate some (precise or approximate) solutions.
