  • Silver Ratio in Maximum Deng Entropy Triangle

    Subjects: Mathematics >> Discrete Mathematics and Combinatorics submitted time 2022-03-18

    Abstract:

    Pascal's triangle is a mathematical triangle of combinatorial numbers, from which Fibonacci number sequence and golden ratio can be obtained. Similarly, silver ratio can be generated based on Pell number sequence. Recently, the relations between Pascal's triangle and maximum Deng entropy (MXDE) are studied and presented. A straightforward question arises: if we design a triangle based on MXDE, what will the associated number sequence and the limiting ratio be like? Hence, this paper proposes a Pascal-like triangle based on MXDE, called the maximum Deng entropy triangle (MDET). Besides, the number sequences based on MDET are investigated. Next, the general term for the MDET sequence is presented and the limiting ratio in MDET sequence is analyzed. We prove that the limiting ratio in the right MDET sequence converges to the silver ratio. Moreover, some examples are given to expound MDET and the MDET sequence.

  • Maximum Entropy of Random Permutation Set

    Abstract: Recently, a new type of set, named as random permutation set (RPS), is proposed by considering all the permutations of elements in a certain set. For measuring the uncertainty of RPS, the entropy of RPS is presented. However, the maximum entropy principle of RPS entropy has not been discussed. To address this issue, in this paper, the maximum entropy of RPS is presented. The analytical solution for maximum entropy of RPS and its corresponding PMF condition are respectively proofed and discussed. Numerical examples are used to illustrate the maximum entropy RPS. The results show that the maximum entropy RPS is compatible with the maximum Deng entropy and the maximum Shannon entropy. When the order of the element in the permutation event is ignored, the maximum entropy of RPS will degenerate into the maximum Deng entropy. When each permutation event is limited to containing just one element, the maximum entropy of RPS will degenerate into the maximum Shannon entropy.

  • QZNs: Quantum Z-numbers

    Subjects: Computer Science >> Integration Theory of Computer Science submitted time 2021-04-12

    Abstract: Because of the efficiency of modeling fuzziness and vagueness, Z-number plays an important role in real practice. However, Z-numbers, defined in the real number field, lack the ability to process the quantum information in quantum environment. It is reasonable to generalize Z-number into its quantum counterpart. In this paper, we propose quantum Z-numbers (QZNs), which are the quantum generalization of Z-numbers. In addition, seven basic quantum fuzzy operations of QZNs and their corresponding quantum circuits are presented and illustrated by numerical examples. Moreover, based on QZNs, a novel quantum multi-attributes decision making (MADM) algorithm is proposed and applied in medical diagnosis. The results show that, with the help of quantum computation, the proposed algorithm can make diagnoses correctly and efficiently.
