A discrete optimization model for preserving biological diversity

A discrete optimization model for preserving biological diversity

In this paper we propose an operational framework within which the concept of diversity is measurable. Based on an interspecies dissimilarity index, we develop a series of progressively more efficient integer programming formulations with the objective of maximizing biological diversity under resource constraints. To illustrate the solution procedure, the model is applied to the preservation of...

A Discrete Hybrid Teaching-Learning-Based Optimization algorithm for optimization of space trusses

In this study, to enhance the optimization process, especially in the structural engineering field two well-known algorithms are merged together in order to achieve an improved hybrid algorithm. These two algorithms are Teaching-Learning Based Optimization (TLBO) and Harmony Search (HS) which have been used by most researchers in varied fields of science. The hybridized algorithm is called A Di...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
