In view of the problems that traditional hotel management and service quality are easily affected by service personnel, and the check-in and check-out procedures are cumbersome, a smart hotel management system based on the combination of IoT and artificial intelligence technology is developed. First, process data collection is used to decompose it into relatively independent Sub-projects, and then use the design structure matrix to express the relationship between the sub-projects, and use the corresponding algorithm to identify the iterative relationship, which provides a feasible idea for project planning and process monitoring. Networking technology realizes centralized control and management of access control and hotel equipment, realizes unmanned service in the whole process from check-in to check-out, and improves efficiency by 7.8%.

In the wireless ubiquitous environment, this paper analyses and models the dynamic volume of access to VOD business. This paper also proposes a wireless business optimization algorithm that enables the CDN edge server to help the core network to divert pressure of user's access best. Firstly, a probability model of the daily volume of access is defined, based on video's score and video's online time. Further, a function relationship between the parameter of the model and the joint conditions above is established to accurately reflect the average value of the daily volume of access. On this basis, the predicted value of the daily volume of access to any video under a certain guarantee probability is obtained. Then, an optimization model for distribution and download of videos is built for the edge server of CDN with limited storage space. A distribution and download scheme of videos based on 0-1 knapsack algorithm is proposed. The simulation results verify the correctness of the model of volume of access and the effectiveness of the optimization algorithm.

A new structure of hydraulic hybrid vehicle (HHV) with hydraulic transformer (HT) was built and the working principle of the new hydraulic hybrid vehicle was described. According to the operating characteristics of HT and energy-saving optimization conditions of accumulator used the HHV;Energy-saving optimization control algorithm with various operation conditions in different working conditions of vehicle was established. Then, simulation analysis to control performance of energy-saving algorithm was carried out using PID, Fuzzy Logic Controller (FLC) and Fuzzy-PID control strategy. Results show that Fuzzy-PID controller has a small influence on the parameters of energy-saving optimization algorithm of the hydraulic hybrid vehicle and maximizing energy recovery can be achieved in different energy states by Fuzzy-PID controller.

In the past few years, deep learning has been used widely in bioinformatics area to solve common problems such as protein sequence prediction, phylogenic inferences, multiple sequence alignment and many more. It has been in the spotlight as a powerful approach which makes significant advances in taking care of the issues that haunt artificial intelligence community for many years. However, several weaknesses such as trap at local minima, lower performance and high computational time still occur in deep learning. Therefore, global optimization technique such as differential search algorithm can be used to assist deep learning method in order to get best finding result and data. This review will cover fundamental of deep learning and their involvement in bioinformatics field as well as implementation of differential search algorithm and their involvement in bioinformatics field.

At present, GIM models face problems in the field of 3D modeling, including the complex hierarchical architecture of the model, the incomplete model classification information, many imaging topology errors of the model, and the non-standardized phenomenon of attribute storage. These problems hinder the effective application and widespread dissemination of GIM models. This makes the fusion of GIM model and geographic information data has not yet reached the ideal state, which makes its digital application scope relatively limited. To solve the above problems, the 3D modeling and optimization method of power grid information model are studied deeply. Therefore, a data storage method based on B-tree structure is proposed, aiming to realize the unified storage of GIM data and the restoration of hierarchy structure. This not only standardizes the storage mode of attribute data, restores the complex hierarchical architecture of the model, but also facilitates the data exchange between different systems, and further promotes the application and development of GIM model. Moreover, because the pole-tower 3D model provided by GIM has some point accuracy problems in the original measurement, this study proposed an optimization algorithm based on adjacent point merging. It improves the accuracy and efficiency of the model data processing, and significantly enhances the visual effect of the model and provides a more solid and comprehensive technical support for the research and application of related fields.

For the irregular nesting problem widely existing in modern manufacturing industry, this paper makes a research on it and presents an optimization algorithm based on no-fit polygon（NFP） method and hybrid heuristic strategy to solve it. The proposed algorithm first uses the composition method of trace line segment to calculate no-fit polygons（NFPs） between every two pieces in piece set, and extracts the candidate placement points for a candidate piece to be placed by using generated NFPs in combination with internal no-fit polygon（INFP） between the piece and the material plate. Then, the algorithm designs and applies three hybrid heuristic strategies to evaluate all candidate pieces and choose the best piece to place next and determine the best placement point for the selected piece. Experimental test has been performed to verify feasibility and effectiveness of the proposed algorithm. The test results show that the algorithm can solve the irregular nesting problem effectively, and improve the utilization of material to a certain extent.

In recent years, with the increasing complexity of system structure and refinement of management, power system optimization computation is facing the double pressure of computational accuracy and computational time. Machine learning (M) techniques can effectively utilize vast historical data to provide new theoretical basis for optimizing stable and fast solutions. This paper is aimed to summarize the optimization algorithm frameworks, which is based on the interaction between M and optimization computing for general power system optimization problems. The framework empowered by M mainly includes end-to-end optimization, ML-enhanced optimization, and joint-driven optimization. By utilizing the physical characteristics of power system, these frameworks not only provide a more efficient and reliable calculation scheme for the optimal operation of power system, but also provide innovative solutions for other complex optimization problems.

The past decades have seen an extensive investigation of evolutionary algorithms. The recombination operators of most evolutionary algorithms are either single-point crossover or multi-point crossover for solving 0-1 combinatorial optimization problems. There is a little studies on excavating the variable relationship to improve the efficiency of the recombination operator. Hence, we propose an optimization algorithm based on excavating variable relationship for solving 0-1 combinational problems. The aim of the recombination operator is fully utilizing the inherent information from every slice component of all individuals. We compared the proposed algorithm with the classic evolutional algorithm with single-point crossover operation on several 0-1 knapsack problems, which is a classical combinatorial optimization problem. The simulation results show the convergence efficiency of the proposed algorithm.
