Articles in Press, Accepted Manuscript, Available Online from 16 November 2020

Abstract
  Clustering is a method of data analysis and one of the important methods in data mining that has been considered by researchers in many fields as well as in many disciplines. In this paper, we propose combining WOA with BA for data clustering. To assess the efficiency of the proposed method, it has been ...  Read More

Volume 6, Issue 3 , Summer 2020, , Pages 119-130

Abstract
  Metaheuristic algorithms are used to solve NP-hard optimization problems. These algorithms have two main components, i.e. exploration and exploitation, and try to strike a balance between exploration and exploitation to achieve the best possible near-optimal solution. The bat algorithm is one of the ...  Read More

3. A New Optimized Hybrid Model Based On COCOMO to Increase the Accuracy of Software Cost Estimation

Ramin Saljoughinejad; Vahid Khatibi

Volume 4, Issue 1 , Winter 2018, , Pages 27-40

Abstract
  The literature review shows software development projects often neither meet time deadlines, nor run within the allocated budgets. One common reason can be the inaccurate cost estimation process, although several approaches have been proposed in this field. Recent research studies suggest that in order ...  Read More
