Solving a Class of Nonlinear Optimal Control Problems Using Haar Wavelets and Hybrid GA

Saeed Nezhadhosein‎; Reza Ghanbari; Khatere Ghorbani-Moghadam

Volume 8, Issue 1 , June 2023, Pages 1-17

  In this paper, we solve a class of nonlinear optimal control problems using a hybrid genetic algorithm (HGA) and a direct method based on the Haar wavelets where the performance index is Bolza-form and the dynamic system is linear‎. ‎First‎, ‎we change the problem by using HWs to a static ...  Read More

A Proximal Method of Stochastic Gradient for Convex Optimization

Zeinab Saeidian; Maryam Mahmoudoghli

Volume 8, Issue 1 , June 2023, Pages 19-32

  ‎The Proximal Stochastic Average Gradient (Prox-SAG+) is a primary method used for solving optimization problems that contain the sum of two convex functions. This kind of problem usually arises in machine learning, which utilizes a large amount of data to create component functions from a dataset. ...  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

The Smallest Number of Colors Needed for a‎ ‎Coloring of the Square of the Cartesian Product of Certain Graphs

Sajad Sohrabi Hesan; Freydoon Rahbarnia; Mostafa Tavakolli

Volume 8, Issue 1 , June 2023, Pages 83-93

  Given any graph G‎, ‎its square graph G^2 has the same vertex set as G, ‎with two vertices adjacent in G^2 whenever they are at distance 1 or 2 in G. ‎‎The Cartesian product of graphs G and H is denoted by G□ H. ‎‎One of the most studied NP-hard problems is the graph coloring ...  Read More
