A survey of some problems in combinatorial designs— a matrix approach

open access: yesLinear Algebra and Its Applications, 1986
In this survey paper matrix theoretic methods dealing with some aspects of the theory of combinatorial designs are discussed. In particular, questions dealing with incidence matrices, quasisymmetric designs, strongly regular graphs, block graphs, special

A Novel Evolutionary Algorithm with Column and Sub-Block Local Search for Sudoku Puzzles [PDF]

open access: yes, 2023
Sudoku puzzles are not only popular intellectual games but also NP-hard combinatorial problems related to various real-world applications, which have attracted much attention worldwide. Although many efficient tools, such as evolutionary computation (EC)

Diagonal Forms, Linear Algebraic Methods and Ramsey-Type Problems [PDF]

open access: yes, 2013
This thesis focuses mainly on linear algebraic aspects of combinatorics. Let N_t(H) be an incidence matrix with edges versus all subhypergraphs of a complete hypergraph that are isomorphic to H. Richard M.

Circular designs balanced for neighbours at distances one and two

open access: yes, 2014
Date of Acceptance: 23/05/2014We define three types of neighbour-balanced designs for experiments where the units are arranged in a circle or single line in space or time.

Dispensing with channel estimation: differentially modulated cooperative wireless communications

open access: yes, 2011
As a benefit of bypassing the potentially excessive complexity and yet inaccurate channel estimation, differentially encoded modulation in conjunction with low-complexity noncoherent detection constitutes a viable candidate for user-cooperative systems ...

Models beyond the Dirichlet process [PDF]

open access: yes
Bayesian nonparametric inference is a relatively young area of research and it has recently undergone a strong development. Most of its success can be explained by the considerable degree of flexibility it ensures in statistical modelling, if compared to

On the theory of Point Weight Designs [PDF]

open access: yes, 2001
A point-weight incidence structure is a structure of blocks and points where each point is associated with a positive integer weight. A point-weight design is a point-weight incidence structure where the sum of the weights of the points on a block is ...

Annual Report 2006 - 2007

open access: yes, 2007
Not AvailableIn agricultural experiments, generally data on more than one character is observed. The experiments, where corresponding to the application of a treatment, more than one response variables are recorded, are known as multi-response ...
