Lower Bounds in Communication Complexity: A Survey
نویسنده
چکیده
We survey lower bounds in communication complexity. Our focus is on lower bounds that work by first representing the communication complexity measure in Euclidean space. That is to say, the first step in these lower bound techniques is to find a geometric complexity measure such as rank, or the trace norm that serves as a lower bound to the underlying communication complexity measure. Lower bounds on this geometric complexity measure are then found using algebraic and geometric tools.

A Survey of Communication Complexity for Proving Lower Bound of Data Structures in Cell-Probe Model
Proving lower bounds for computational problem is always a challenging work. In this survey, we will present some techniques for proving lower bound of data structures in cellprobe model. There is a natural relationship between cell-probe model and communication complexity, so many proofs of lower bound in cell-probe model are related to communication complexity. In communication complexity, th...
متن کاملLower Bounds in Communication Complexity
The communication complexity of a function f(x, y) measures the number of bits that two players, one who knows x and the other who knows y, must exchange to determine the value f(x, y). Communication complexity is a fundamental measure of complexity of functions. Lower bounds on this measure lead to lower bounds on many other measures of computational complexity. This monograph survey lower bou...
متن کاملCommunication Complexity
The disjointness problem is one of the most important questions in communication complexity, and lower bounds for disjointness have been used to derive lower bounds for streaming algorithms, data structures, barriers in complexity (algebraization), approaches for circuit lower bounds, proof complexity, game theory. Some sources on this include the survey “The Story of Set Disjointness” by Chatt...
متن کاملComplexity Lower Bounds using Linear Algebra
We survey several techniques for proving lower bounds in Boolean, algebraic, and communication complexity based on certain linear algebraic approaches. The common theme among these approaches is to study robustness measures of matrix rank that capture the complexity in a given model. Suitably strong lower bounds on such robustness functions of explicit matrices lead to important consequences in...
متن کاملLower Bounds Using Kolmogorov Complexity
In this paper, we survey a few recent applications of Kolmogorov complexity to lower bounds in several models of computation. We consider KI complexity of Boolean functions, which gives the complexity of finding a bit where inputs differ, for pairs of inputs that map to different function values. This measure and variants thereof were shown to imply lower bounds for quantum and randomized decis...
