Unidimensional Search Scheme Using Identric Mean for Optimization Problems

OPSEARCH, 2001
In this paper, a new unidimensional search scheme called Identric mean (IM) scheme is proposed. Numerical results on five test functions show that the proposed IM method is superior to the existing RMS method in the literature.

Improvements of Inequalities for Sándor and Identric Means with Applications

World Journal of Mathematics and Statistics
This paper is devoted to establishing the best possible upper and lower bounds for the Sándor mean and the identric mean in terms of the harmonic and arithmetic means. These two means, which are closely related to other classical means such as the logarithmic and Seiffert means, have attracted considerable attention in recent studies due to their rich ...

A sharp double inequality involving identric, Neuman-Sándor, and quadratic means

SCIENTIA SINICA Mathematica, 2013
本文证明了双向不等式 αI ( a; b )+(1- α ) Q ( a; b ) M ( a; b ) βI ( a; b )+(1- β ) Q ( a; b ) 对所有不相等的正实数 a 和 b 成立当且仅当 α ≥1/2 和 β ≤[e(√2log(1+√2)-1)]/[(√2e-2) log(1+√2)]=0:4121…,其中 I(a; b), M(a; b) 和 Q(a; b) 分别表示 a 和 b 的指数平均、Neuman-Sandor平均和二次平均.
