Efficient Solution of Nonlinear Unconstraint Optimization Problems using Quasi-Newton's Method‎: ‎A Revised Approach

Hajar Alimorad

Volume 9, Issue 1 , May 2024, , Pages 49-65

  While many real-world optimization problems typically involve multiple constraints, unconstrained problems hold practical and fundamental significance. They can arise directly in specific applications or as transformed versions of constrained optimization problems.‎ ‎Newton's method‎, ...  Read More

Optimal Edges in Morphological Snakes

Rasool Hatamian Joghali

Volume 8, Issue 1 , June 2023, , Pages 55-67

  In 2010, Alvarez et al. proposed an algorithm for morphological snakes that could detect objects whose edges consist of convex sets and polygonal edges. However, the algorithm may not detect the boundary well if the edges of an object contain a convex set or if there are several separated ...  Read More

On Grey Graphs and their Applications in Optimization

Mohammad Hamidi; Kamal Norouzi‎; Akbar Rezaei

Volume 6, Issue 2 , July 2021, , Pages 79-96

  In this research‎, ‎we use averages and relative measures of interval grey numbers to introduce grey vertices, ‎grey edges‎, ‎and grey graphs (graphs are based on interval grey numbers)‎. ‎To do so‎, ‎we design a grey graph based on a graph (as the underlying graph)‎. ...  Read More

Optimal Shape Design for a Cooling Pin Fin Connection Profil

Seyed Hamed Hashemi Mehne; Khodayar Javadi

Volume 2, Issue 2 , December 2017, , Pages 61-76

  A shape optimization problem of cooling fins for computer parts and integrated circuits is modeled and solved in this paper. The main purpose is to determine the shape of a two-dimensional pin fin, which leads to the maximum amount of removed heat. To do this, the shape optimization problem is defined ...  Read More
