Variants on the minimum rank problem: A survey II∗

چکیده
1 The minimum rank problem for a (simple) graph G is to determine the smallest possible 2 rank over all real symmetric matrices whose ijth entry (for i 6= j) is nonzero whenever {i, j} 3 is an edge in G and is zero otherwise. This paper surveys the many developments on the 4 (standard) minimum rank problem and its variants since the survey paper [36]. In particular, 5 positive semidefinite minimum rank, zero forcing parameters, and minimum rank problems for 6 patterns are discussed. 7

The Minimum Rank of Symmetric Matrices Described by a Graph: A Survey
The minimum rank of a simple graph G is defined to be the smallest possible rank over all symmetric real matrices whose ijth entry (for i 6= j) is nonzero whenever {i, j} is an edge in G and is zero otherwise. This paper surveys the current state of knowledge on the problem of determining the minimum rank of a graph and related issues.
متن کاملA Comparison of NSGA II and MOSA for Solving Multi-depots Time-dependent Vehicle Routing Problem with Heterogeneous Fleet
Time-dependent Vehicle Routing Problem is one of the most applicable but least-studied variants of routing and scheduling problems. In this paper, a novel mathematical formulation of time-dependent vehicle routing problems with heterogeneous fleet, hard time widows and multiple depots, is proposed. To deal with the traffic congestions, we also considered that the vehicles are not forced to come...
متن کاملOn the graph complement conjecture for minimum rank
The minimum rank of a graph has been an interesting and well studied parameter 6 investigated by many researchers over the past decade or so. One of the many unresolved questions on 7 this topic is the so-called graph complement conjecture, which grew out of a workshop in 2006. This 8 conjecture asks for an upper bound on the sum of the minimum rank of a graph and the minimum rank 9 of its comp...

متن کاملMinimum Rank Problems
A graph describes the zero-nonzero pattern of a family of matrices, with the type of graph (undirected or directed, simple or allowing loops) determining what type of matrices (symmetric or not necessarily symmetric, diagonal entries free or constrained) are described by the graph. The minimum rank problem of the graph is to determine the minimum among the ranks of the matrices in this family; ...
