Konuşmacı: Fatih Demirkale, Ph.D (Koç Üniversitesi)

Başlık: Orthogonal Arrays; Enumeration and Applications

Özet: Orthogonal arrays are used in the design of experiments in
statistics, in computer science as well as in many fields of combinatorics.
In this talk, I will give an application of orthogonal arrays to construct
D-optimal discrete choice experiments.

Later, I will address the existence problem of orthogonal arrays, and I
will describe new algorithms to enumerate all orthogonal arrays with given
parameters. Key techniques include eliminating significant space
requirements, using previously-computed information on substructures in an
efficient way. Computational results show these algorithms to be
significantly faster than the prior state-of-the-art.

Lastly, I will define the linear independence of Latin squares and I will
state a basis for a linear space which contains all Latin squares. I will
use this theory to study an asymptotic formula for the number of orthogonal
arrays with three columns.
