Boas' Formula and Sampling Theorem
In 1937, Boas gave a smart proof for an extension of the Bernstein theorem for trigonometric series. It is the purpose of the present note (i) to point out that a formula which Boas used in the proof is related with the Shannon sampling theorem; (ii) to present a generalized Parseval formula, which is suggested by the Boas’ formula; and (iii) to show that this provides a very smart derivation o...
متن کاملA Meta-heuristic Algorithm for Global Numerical Optimization Problems inspired by Vortex in fluid physics
One of the most important issues in engineering is to find the optimal global points of the functions used. It is not easy to find such a point in some functions due to the reasons such as large number of dimensions or inability to derive them from the function. Also in engineering modeling, we do not have the relationships of many functions, but we can input and output them as a black box. The...
متن کاملAn Efficient Optimization Algorithm for Super High Dimensional Numerical Function Inspired by Cellular Differentiation
Inspired by the cellular differentiation behaviors, a new biomimetic optimization algorithm, cellular differentiation optimization algorithm (CDOA), is proposed. First, a certain number of cells are randomly distributed in the search space in which each cell represents a solution. Then, several cellular differentiation behaviors such as division, growth, migration, adhesion and apoptosis are ex...
متن کاملCoordinated Hunting by Cuban Boas
Coordinated hunting, in which individual predators relate in time and space to each other’s actions, is uncommon in animals, and is often difficult to distinguish from simply hunting in non-coordinated groups, which is much more common. The author tested if Cuban boas (Chilabothrus angulifer) hunting bats in cave passages take into account other boas’ positions when choosing hunting sites, and ...
متن کاملA Numerical Optimization Algorithm Inspired by the Strawberry Plant
This paper proposes a new numerical optimization algorithm inspired by the strawberry plant for solving complicated engineering problems. Plants like strawberry develop both runners and roots for propagation and search for water resources and minerals. In these plants, runners and roots can be thought of as tools for global and local searches, respectively. The proposed algorithm has three main...
