In this paper, an enhanced estimation of distribution algorithm (EEDA) is proposed to solve the hybrid flow-shop scheduling problem with identical parallel machines to minimize makespan. To evaluate the individuals, some decoding rules including the improved permutation scheduling rule, the improved list scheduling rule and the backward scheduling rule are designed for the permutation-based encoding scheme, and then a hybrid decoding method is proposed. To describe the distribution of the solution space for the EEDA, a probability model is built and used to generate new individuals by sampling. To well trace the region with promising solutions, a mechanism is provided to update the model with the superior sub-population. To enhance the exploitation capability, multiple local search operators are incorporated in the framework of the EEDA. The influence of the parameter setting is investigated based on the Taguchi method of design-of-experiment. Extensive numerical testing results based on sets of the well-known benchmarks and the comparisons with some existing algorithms demonstrate the effectiveness of the proposed algorithm.

GENERALIZED TYPE-II HYBRID ARQ

ELECTRONICS LETTERS 1990年第2期26卷 88-89页

The letter gives general descriptions of II-GHARQ and defines a concept of minimum distance distributed sequence (DDS) which is more exact to represent the error-correcting capability of the codes used in II-GHARQ. Some DC codes which have a better DDS than KM codes are designed and Hadamard transform decoding is regarded as a common decoding method. Both analysis and simulation results indicate that II-HARQ using DC code gives a good throughput efficiency.

A particle swarm optimization algorithm for open vehicle routing problem

EXPERT SYSTEMS WITH APPLICATIONS 2011年第9期38卷 11547-11551页

This paper presents a real-value version of particle swarm optimization (PSO) for solving the open vehicle routing problem (OVRP) that is a well-known combinatorial optimization problem. In OVRP a vehicle does not return to the depot after servicing the last customer on a route. A particular decoding method is proposed for implementing PSO for OVRP. In the decoding method, a vector of the customer's position is constructed in descending order. Then each customer is assigned to a route with taking into account feasibility conditions. Finally one-point move has been applied on constructed routes that seem promising to result in a better solution. Experimental evaluations on benchmark data sets demonstrate the competitiveness of the proposed algorithm. (C) 2011 Elsevier Ltd. All rights reserved.

Reproduction accuracy of Higher-Order Ambisonics with Max-rE and/or least norm solution in decoding

In sound field reproduction with Higher-Order Ambisonics (HOA), a sweet spot is formed around a reproduction point that is generally a center of spherical loudspeaker array. The conventional HOA decoding with a unique solution yields a spherical sweet spot, in which the reproduction error is less than 4% and whose radius is theoretically defined in the literature. On the other hand, it is known that Max-rE decoding or a least norm solution derived when using a larger number of loudspeakers would lead to an enhancement of reproduction accuracy. However, it is yet to be revealed how Max-rE decoding and the least norm solution affects the reproduction accuracy and the size and shape of the sweet spot, when they are individually or simultaneously applied to HOA decoding. This paper numerically investigates the reproduction accuracy of HOA with such different HOA decoding methods. The numerical results suggest that, compared to the conventional decoding method, ones with Max-rE and/or the least norm solution result in deformed or expanded sweet spot and suppression of reproduction errors outside the sweet spot.

k-order Gaussian Fibonacci polynomials and applications to the coding/decoding theory

In this paper we define k-order Gaussian Fibonacci polynomials with boundary conditions and give the generating function, explicit formula and some identities for k-order Gaussian Fibonacci polynomials. We introduce the matrix represent and we obtain the k-order Gaussian Fibonacci Polynomials matrix. We define a new coding theory called k-order Gaussian Fibonacci Polynomials coding theory and establish the code elements for values of k. This coding/decoding method bound to the Q(k) (x), R-k (x) and E-k,E-n (x) matrices. So, this method is different from the classical algebraic coding. Consequently, with this method, we move the coding theory onto a complex space which is a different field. Therefore, new working areas are created.

Trellis-coded pulse-amplitude modulation (TC-PAM) is applied in visible light communication (VLC) system using RGB-LED. Based on natural modulation, we propose a modified modulation to yield performance enhancement. Further, a decoding method of combing soft-decision Viterbi algorithm with most significant bit (MSB) decoding is developed. Finally, the results of Monte-Carlo simulation are presented to verify the best modulation and decoding method among the mentioned modulation and decoding techniques.

In this paper, we introduce a new decoding method to mitigate the issue of hallucinations in Large Language Models (LLMs). Specifically, our method dynamically selects appropriate internal layers(DiLa) of the model and compares their logic to enhance the authenticity and accuracy during the decoding process. Experimental results show that DiLa significantly improves performance across multiple tasks without fine-tuning the model and without substantially reducing decoding efficiency. Overall, our approach is a simple yet efficient solution to alleviate the hallucination problem in LLMs.

KEELOQ code hopping technology is a nonlinear anti-encryption algorithm designed for secure Remote Keyless Entry (RKE) systems. It combines a 66-bits transmission length, so as to prevent the system from code predicting, code grabbing and code scanning. Because of its feature of high-security, it effectively overcomes the disadvantages of the traditional fixed code technology. This paper researched on KEELOQ encryption algorithm and presented a designed RKE system based on KEELOQ technology. When the software and hardware were designed, the whole RKE system was afterwards made as a prototype for the functionality tests. The experimental results showed that the design achieved the anticipative effects.
