On the condition numbers for polyhedra in Karmarkar's form
We present formulations of two condition measures (one for linear programming (LP) due to Ye, and the other for a matrix) as optimization problems over sign constraints. We construct, based on LP duality, a dual characterization of Ye's condition measure in the setting of Karmarkar's form. The elementary formulations (without utilizing the dual characterization) lead to trivial proofs of some r...
متن کاملCondition number of Bott-Duffin inverse and their condition numbers
Various normwise relative condition numbers that measure the sensitivity of Bott– Duffin inverse and the solution of constrained linear systems are characterized. The sensitivity of condition number itself is then investigated. Finally, upper bounds are derived for the sensitivity of componentwise condition numbers. 2002 Elsevier Science Inc.

متن کاملData Type for Real Numbers . ⋆
We present a calculus having real numbers as a basic data type. The calculus is defined by its denotational semantics. We prove the universality of the calculus. We show how the definition of an operational semantics is problematic. We discuss this problem and present a possible solution.
متن کاملComprehending Real Numbers: Development of Bengali Real Number Speech Corpus
Speech recognition has received a less attention in Bengali literature due to the lack of a comprehensive dataset. In this paper, we describe the development process of the first comprehensive Bengali speech dataset on real numbers. It comprehends all the possible words that may arise in uttering any Bengali real number. The corpus has ten speakers from the different regions of Bengali native p...
متن کاملTools for visualizing real numbers: Planar number walks
Motivated by the desire to visualize large mathematical data sets, especially in number theory, we offer various tools for representing floating point numbers as planar (or three dimensional) walks and for quantitatively measuring their “randomness.”
