Improving Speed and Efficiency of Dynamic Programming Methods through Chaos

H. Khodadadi; V. Derhami

Volume 9, Issue 4 , November 2021, , Pages 487-496

  A prominent weakness of dynamic programming methods is that they perform operations throughout the entire set of states in a Markov decision process in every updating phase. This paper proposes a novel chaos-based method to solve the problem. For this purpose, a chaotic system is first initialized, and ...  Read More

A New Method for Encryption of Color Images based on Combination of Chaotic Systems

H. Khodadadi; A. Zandvakili

Volume 7, Issue 3 , July 2019, , Pages 377-383

  This paper presents a new method for encryption of color images based on a combination of chaotic systems, which makes the image encryption more efficient and robust. The proposed algorithm generated three series of data, ranged between 0 and 255, using a chaotic Chen system. Another Chen system was ...  Read More

A stack-based chaotic algorithm for encryption of colored images

H. Khodadadi; O. Mirzaei

Volume 5, Issue 1 , March 2017, , Pages 29-37

  In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic ...  Read More
