Note on two - phase method for a class of metric models in individual scaling
(2010-03-12)
This working paper the authors discuss the typical problem in individual scaling viz., finding a common configuration and weights attached to dimensions for each individual from the given interpoint distances or scalar products.
Necessary and sufficient condition for a matrix to be totally unimodular
(2010-03-13)
A characterization of totally unimodular matrix is gives is the paper. This provides an iterative method directly applicable on the matrix itself to recognize total unimodularity or otherwise of any given matrix.
On the computation of Hodges-Lehmann efficiency of test statistics
(2010-03-13)
An approach to the computation of Bahadur Efficiency was proposed by Bahadur and Raghavachari in their paper in Proceedings of Sixth Berkeley Symposium. The objective of the paper is to exhibit this approach to the Computation ...
Some properties of optimal schedule of jobs with a common due date
(2010-03-13)
Kanet (Naval Research Logistics Quarters, 1981) considered the problem of minimizing the average deviation of job completion times above a common due date. Under the condition that the common due date exceeds the makespan ...
A geometric programming approach to solve van der waerden conjecture on doubly stochastic matrices
(2010-03-13)
In this paper the problem of finding the minimum of the permanent of a doubly stochastic matrix has been formulated as a reversed geometric program with a single constraint and an equivalent dual formulation is given. A ...
Mathematical programming method to determine exact optimum allocation in stratified random sampling
(2010-03-20)
In this paper an exact integer programming formulation is proposed and an efficient method of finding optimal solution is given. An alternative method using incremental or marginal analysis approach is also given. A numerical ...
