Unified Particle Swarm Optimization for Hadamard matrices of Williamson type
In this work we apply the recently proposed Unified Particle Swarm Optimization (UPSO) method to the search for Hadamard matrices of the Williamson type. The objective functions that arise from the classical Williamson construction, are ideally suited for UPSO algorithms. This is the first time that swarm intelligence methods are applied to this problem. Mathematics Subject Classification (2000...
متن کاملSYMMETRIC BUSH-TYPE HADAMARD MATRICES OF ORDER 4m EXIST FOR ALL ODD m
Using reversible Hadamard difference sets, we construct symmetric Bush-type Hadamard matrices of order 4m4 for all odd integers m.
متن کاملOn the asymptotic existence of complex Williamson Hadamard matrices
It is shown that for each odd integer q, there is a complex WilliamsonHadamard matrix of order 2(q)+1 ·2n (q)+1 . q. In a recent paper Craigen, Holzmann and Kharaghani [1] showed that for every odd integer q) there is an integer N( q) which does not exceed twice the number of nonzero digits in the binary expansion of q, such that the existence of an Orthogonal Design (OD) of order 2N (q)-1 impl...
