System Modeling And Identification
Part of the Lecture Notes in Computer Science book series (LNCS, volume 3)


The problem of finding the best size for the system model is considered. By explicitly synthesizing the complexity cost of a proposed model, one is able to transform this problem into a constrained integer programming problem.
