1. Optimal Design of Open Channel Sections Using PSO Algorithm

Mohsen Monadi; Mirali Mohammadi; Hamed Taghizadeh

Volume 11, Issue 2 , Autumn 2019, , Pages 207-215

Abstract
  This paper applies an evolutionary algorithm, the particle swarm optimization (PSO), to design the optimum open channel section. Depth, channel side slope and bottom width are considered as the variables for rectangular, triangular and trapezoidal channels, respectively. The objective function is minimizing ...  Read More

2. Flying Squirrel Optimizer (FSO): A novel SI-based optimization algorithm for engineering problems

Gholamreza Azizyan; Farid Miarnaeimi; Mohsen Rashki; Naser Shabakhty

Volume 11, Issue 2 , Autumn 2019, , Pages 177-205

Abstract
  This paper provides a novel meta-heuristic optimization algorithm. The behaviors of flying squirrels in the nature are the main inspiration of this research. These behaviors include flying from tree to tree and walking on the ground or on a tree branch to find food. They also contact each other with ...  Read More

3. Optimization of solution stiff differential equations using MHAM and RSK methods

Shadan Sadigh Behzadi

Volume 11, Issue 1 , Spring 2019, , Pages 17-21

Abstract
  In this paper, a nonlinear stiff differential equation is solved by using the Rosenbrock iterative method, modified homotpy analysis method and power series method. The approximate solution of this equation is calculated in the form of series which its components are computed by applying a recursive ...  Read More

4. Important Issues in Multiple Response Optimization

Mohammad Taleghani

Volume 3, Issue 1 , Winter 2011, , Pages 189-200

Abstract
  There have been many productive methods developed so far for optimization of multiple response surface (MRS) problems. This paper tends to review the most seminal approaches in MRS and discuss the strength and weakness of each of the approaches through existing aspects in MRS. A numerical example is ...  Read More

5. Designing an optimization model for preventing the waste time in the activity cycle of an organization

M. Taleghani; Y. Modabbernia

Volume 1, Issue 2 , Summer 2009, , Pages 67-76

Abstract
  This article proposes an optimization model for preventing the waste of time in the educational and research activities' cycle of an organization such as a university. For this purpose and in order to increase efficiency and prevent the waste of time; the graph theory models have been used. The educational ...  Read More
