Cyclic Polygonal Designs with Block size 3 and Joint Distance 3 [PDF]

open access: yesPakistan Journal of Commerce and Social Sciences, 2011
polygons, are useful in survey sampling in terms of balanced sampling plans excluding contiguous units (BSECs) and balanced sampling plans excluding adjacent units (BSAs) when neighboring units in a population provide similar information.

Learning Robust Search Strategies Using a Bandit-Based Approach

open access: yes, 2018
Effective solving of constraint problems often requires choosing good or specific search heuristics. However, choosing or designing a good search heuristic is non-trivial and is often a manual process.

Optimal BIBD-extended designs

open access: yes, 2019
Balanced incomplete block designs (BIBDs) are a class of designs with v treatments and b blocks of size k that are optimal with regards to a wide range of optimality criteria, but it is not clear which designs to choose for combinations of v, b and k when BIBDs do not exist.

Some techniques for constructing infinite families of BIBD'S

open access: yesDiscrete Mathematics, 1983
AbstractHadamard systems and balanced weighing systems, generalizing Hadamard matrices and balanced weighing matrices respectively, are defined and their properties are examined. Some of these systems are constructed and then used in constructing infinite families of BIBD's.
