Introduction
At present, computer technology and Internet technology have been integrated into all corners of society, greatly affecting and changing our production and lifestyles, and providing people with great convenience. From the time when the Internet was underdeveloped to the present, the convenience of Internet technology has affected all walks of life. Among them, education is a national priority and key development business, and informatization has also been applied early in education. Educational information e concept of chemistry has also begun to be widely recognized and valued. In recent years, with the continuous improvement of my country's education level, some schools have begun to use information management systems in order to provide their own management and teaching levels. According to their own teaching management characteristics, they have designed and developed a series of education information management platforms to promote teaching Management work is developing in the direction of informatization. e emergence of a networked hybrid teaching management system has brought major reforms to the hybrid teaching management, informatization construction, sharing and release of teaching resources, networked educational administration and comprehensive management of student information in colleges and universities, and many colleges and universities have burst out e new teaching management ideas are all benefited from the rapid development of networking and informatization. As a brand-new management method, the hybrid teaching management system is an important application of computer technology in the field of education. It strengthens the comprehensive management of schools, improves the efficiency of teachers, and advances the process of university management. At present, from a technical perspective, the current teaching management system used by private training institutions is mainly based on the C/S architecture.
is architecture is simple in structure and easy to develop. e internal staff of the training institution can complete the development or commission small software e development work is done on behalf of the development, generally the cost is low, and it is widely used in small training institutions. For colleges and universities, C/S architecture is usually difficult to meet their needs, and they mostly use teaching management systems based on B/S architecture. e B/S architecture system is more difficult to develop than the C/S architecture, but it has more powerful functions and is more suitable for school use scenarios. e B/S structure system is easy to maintain, which is conducive to the expansion of the school. On the other hand, the B/S architecture adopts a modular system architecture, and the internal modules of the system are loosely coupled, which facilitates the expansion of the department and the increase of system functions, and is more suitable for changes in the teaching management business of colleges and universities. According to the school's mixed teaching management business needs and the needs of information construction, it is very necessary to design and develop an information management system suitable for the school's own development.
rough the design and implementation of this system, it can not only improve daily work and student management Efficiency, but also can reduce costs, improve their own competitiveness, and better provide students with a good learning environment and conditions.

MVC Architecture.
e whole university hybrid teaching management system mainly adopts the objectoriented design method for development and design.
rough comparison and analysis, the system architecture design selection is based on the MVC (Model View Controller) architecture method. rough the use of MVC e architecture system can effectively improve the scalability and maintainability of the system. At the same time, the code reusability can be further improved in the system development process, which is convenient to reduce the system development cycle and the development cost can also be reduced. e specific situation of the relationship between the layers of the entire MVC architecture is shown in Figure 1. e entire MVC architecture is mainly composed of three parts: view, model, and controller. Among them, the view part is mainly able to provide system users with a human-computer interaction interface, which can collect user specific operations, and can also display the content processed through the model layer. Normally, the view part is usually made of HTML elements. With the continuous development of computer technology, this module can be used to query the status of the model part and check the status change of the controller module. With the continuous development of computer technology, in order to be able to continuously enrich the machine interaction operation, provide users with more convenient and efficient interaction Experience, XML and Flash and many other elements are being applied. e model part is used to process various different types of data according to certain logic. is module can be used to query the status of the view part. In order to effectively improve the processing capabilities of various types of data, usually one model can be combined with multiple view blocks. Correspondence and processing. e controller part is the most core part of the entire MVC architecture. It can coordinate the information interaction between the view part and the model part, and process the user time information fed back by the view module to ensure the stable and reliable operation of the system. Combined with the MVC architecture diagram, it can be seen that after the user sends an operation request by using the model module in the MVC architecture, the system can call the user's specific operation request by using the view module, and at the same time feed back user event information to the controller. e controller will further retrieve the processing task data in the model module, and display the feedback and specific content information retrieved to the system user through the view module [1][2][3][4][5][6] It can greatly satisfy the effective management of the current university teaching system.

Basic Mathematical Model.
e basic genetic algorithm consists of 8-tuples in the following formula, namely: (1) In formula (1): S-represents the individual coding method (binary), which is the basic factor in genetic algorithm. A combination formed by the connection of genes and chromosomes is a solution for curriculum arrangement; F-represents the fitness evaluation function of the individual. Use this function value to distinguish whether the individual meets the requirements; P0-represents the initial group, a combination of courses randomly formed by genetic algorithm, and subsequent optimization of genetic algorithm will be carried out around the initial group; N--represents the size of the group; V--represents the selection operator, and the calculation method is filtered by the fitness value. Generally, the larger the value, the easier it is to be selected; [--represents the crossover operator. e new individual is generated by the random exchange of genes from the parent individual, and the single point crossover method is adopted; ψ-represents the mutation operator, the parent individual randomly changes the individual's own gene value, and adopts a single point mutation of the gene; T--represents the termination condition of the algorithm. When performing genetic iteration, we generally set a certain parameter value, and the operation is terminated when the parameter is iterated algebraically [7].

Operation Process.
When using genetic algorithms to develop a hybrid teaching system, follow the steps below: (1) Choose an appropriate way to encode system parameters, and convert the relatively optimized solution set into chromosomes for representation; (2) Determine the initial group of the system; (3) Define the fitness function; (4) Genetic operation of the design system; (5) Control the setting of parameters such as the size of the population and the probability of genetic manipulation; (6) Judge whether the generated group meets a specified index, if it is satisfied, exit the calculation, if it is not satisfied, return to the operation of calculating the fitness function value [8]. e specific flow chart is shown in Figure 2.

System Architecture Design.
In order to facilitate the system to have stronger scalability and maintainability, in the process of architecture selection, the MVC architecture is finally selected as the system architecture of the college online teaching management system, combined with specific design, the entire college online hybrid teaching management system e detailed design of the overall architecture is shown in Figure 3. e overall architecture of this hybrid teaching management system is mainly composed of the presentation layer, the system service layer and the data layer. e presentation layer is mainly used to provide access interfaces for system users of the university hybrid teaching management system. rough the front-end operation interface of this layer, users can provide interface services for various business operations in the system service layer [9]. e system service layer is mainly composed of core business and business support parts. e core business part specifically includes the operation of system management, online learning management and other business functions. At the same time, in order to provide strong support for the main core business operations, in this layer e business support part has designed user authority configuration and information query and information exchange services. e data layer is mainly used to provide services for the retrieval and storage of all data information in the hybrid teaching management system of colleges and universities, and to provide data support for the smooth progress of various core businesses in the system service layer. e business functions to be realized mainly include a variety of data information such as online course information database and video-on-demand course information database [10,11].

System Network Topology
Design. By combining the overall architecture of the system, it can be seen that the entire university hybrid teaching management system mainly adopts the MVC three-tier architecture. In order to meet the characteristics of the scattered users of the system combined with the characteristics of the system architecture, the specific network topology structure diagram of the university hybrid teaching management system e design is shown in Figure 4.
It can be clearly found that in the course of business operation of the college hybrid teaching management system, all users in the system can use the external network and the college intranet for system login access, and the terminal devices used are computers. e network architecture can be divided into the core area and the gatekeeper isolation area. For the core area, its firewall can effectively guarantee the security performance of the system. e main method is the connection between the load balancing server and the gatekeeper isolation area, thereby providing access to the database in this area. Manage and control servers and application servers [12][13][14].

System Function Module Design.
Online learning management is an important module of the entire university's hybrid teaching management system. It is mainly used by teachers to create, review and publish online courses. College students can also use this function for online course inquiry and registration. Combined with actual needs, the design of the functional structure diagram of the specific online learning management module is shown in Figure 5. e entire online learning management module mainly includes three sub-functions: online course management, my course management, and online learning. e online course management sub-module is composed of two main functions: online course creation and online course review and release. e entire course management sub-module is composed of three main functions: online course inquiry, online course registration, and my course inquiry. By combining the actual needs and target requirements of the college, students can use this module to query relevant course information and combine e training goal requires course application and registration, and at the same time, it is possible to Computational Intelligence and Neuroscience inquire in detail about the course status declared by the individual. e online learning sub-module is composed of three main functions: course study material management, course video on demand, and online interaction. In combination with the online learning function requirements, the detailed online learning data management work sequence diagram is shown in Figure 6. For the various video materials uploaded by users, the system administrator is responsible for categorizing them and sorting them according to the number of views. At the same time, they set tags for each video so that users can easily and quickly find what they need through search and other means. Video learning, in the search process, on the one hand, the system administrator can combine with the actual situation to directly query the ranking of the popular course videos, on the other hand, it can also directly search through the input of the course keywords. When students are learning on video-on-demand, they can use the interactive module to leave a message and ask questions at any time, and the teacher in charge can answer questions through the interactive platform after seeing the student's message [15].
Combined with the working sequence diagram of the hybrid teaching management system, it can be known that the system operator clicks "online learning management" on the operation homepage, then enters "online learning," and then completes the specific creation of the course video materials according to actual needs, and completes the course video Upload and edit on-demand resource information. After the operation is completed, after the course video on-demand resource information database is updated, college students can search for course video-on-demand resources. After entering the required query on-demand resource keywords, the system will combine the input keywords e matching information is screened in the database, and then the     Computational Intelligence and Neuroscience qualified resource information is displayed. In the process of watching the on-demand video, the college students can enter the interactive information of the course.

System Database Design.
e database logical structure design is the design of the overall logical structure of the database. e design methods mainly include top-down, bottom-up and one-by-one ree kinds of expansion. Among them, the top-down is mainly through the design of the overall data structure, and then gradually refines until the design of the entire data structure is completed; bottomup merges the data structure according to the logical relationship between the data, until the overall data structure is completed the design of. Combining the detailed design of the overall E_R diagram of the university hybrid teaching management system and the specific data logic structure rules, the design of the main data information tables such as online course information, test paper information and basic learning file information included in the system is explained.
For a detailed description of the online course information table, see Table 1. According to the design of the online course information table, combined with the corresponding data logical structure, this information table is composed of course name, instructor, course hours, course credits, and course duration.
