Special Issue Information

Dear colleagues,

There is a lot of work involved in applying symmetry and asymmetry to computer science and e-learning problems. We are faced with symmetry in data structures, sequences, and time series. We meet symmetry in algorithms of different classes and problems from different fields. Neural networks, bio-inspired and evolutionary algorithms, N-version software, encryption algorithms, blockchain, and software and hardware systems for education and e-learning are often characterized by symmetry or, on the contrary, asymmetry. Symmetry is an exceptional characteristic that has widely been deployed in diverse research fields of software engineering and e-learning.

This Special Issue is intended to present recent progress and developments in the fields of software engineering and e-learning. Interested researchers are invited to submit their work in the form of original research papers or review articles. We welcome original contributions to a variety of emerging areas, including (though not limited to) software engineering, software dependability, object-oriented technology,  programming languages, artificial intelligence, machine leaning, data mining, neural networks, genetic and evolutionary algorithms, human–computer interaction, virtual reality and computer graphics, computer animation, visual and multimedia computing,  render optimization, software economics and metrics, cost modeling and analysis, forecasting and decision support, econometrics, blockchain, Internet and information systems, web-based applications, e-learning, distance education, massive open online courses, and learning management systems.

Ideas related to the systematization of educational technologies are of great interest. This is due, among other things, to the principles of symmetry. On the basis of their application, the synthesis of well-established facts and principles in international education will be realized. Practical needs that are directed towards the future will also be realized. This paper is devoted to the study and creation of a methodology that makes it possible to evaluate the resource efficiency of an interethnic digital platform. The developed methodology of resource allocation for the promotion of digital educational programs is unified and can be applied in any region or country. Considering the specific legislative acts on the financial support of higher education and the need for professionals in certain areas, this method allows you to give a qualitative assessment and determine the necessary resources for the development and promotion of an interethnic digital educational platform, identifying the most appropriate areas of education depending on the region or country.

With database management systems becoming complex, predicting the execution time of graph queries before they are executed is one of the challenges for query scheduling, workload management, resource allocation, and progress monitoring. Through the comparison of query performance prediction methods, existing research works have solved such problems in traditional SQL queries, but they cannot be directly applied in Cypher queries on the Neo4j database. Additionally, most query performance prediction methods focus on measuring the relationship between correlation coefficients and retrieval performance. Inspired by machine-learning methods and graph query optimization technologies, we used the RBF neural network as a prediction model to train and predict the execution time of Cypher queries. Meanwhile, the corresponding query pattern features, graph data features, and query plan features were fused together and then used to train our prediction models. Furthermore, we also deployed a monitor node and designed a Cypher query benchmark for the database clusters to obtain the query plan information and native data store. The experimental results of four benchmarks showed that the average mean relative error of the RBF model reached 16.5% in the Northwind dataset, 12% in the FIFA2021 dataset, and 16.25% in the CORD-19 dataset. This experiment proves the effectiveness of our proposed approach on three real-world datasets. Full article
