内容説明
How to compute a linear Boolean operator by a small circuit using only unbounded fanin addition gates? Because this question is about one of the simplest and most basic circuit models, it has been considered by many authors since the early 1950s. This has led to a variety of upper and lower bound arguments-ranging from algebraic (determinant and matrix rigidity), to combinatorial (Ramsey properties, coverings, and decompositions) to graph-theoretic (the superconcentrator method).
Complexity of Linear Boolean Operators is the first thorough survey of the research in this area. The focus is on cases where the addition operation is either the Boolean OR or XOR, but the model in which arbitrary Boolean functions are allowed as gates is considered as well. The survey is intended for students and researchers in discrete mathematics and theoretical computer science. No special background in computational complexity is assumed and the text is also accessible to senior undergraduates. The insightfulness of the arguments presented here invites the reader to delve deeper and hopefully conquer this ""complexity Waterloo'': to prove a superlinear lower bound for XOR circuits.
