Approaches to solving the dynamic load dispatch problem for an isolated power system consisting of power stations and consumers are considered. The distinction of this task is moving during day power demand. The transition from a problem with constraints characterizing the physical and operational properties of power generators to a problem without ones but with the use of fines functions is described. Two swarm intelligence algorithms were used: particle swarm optimization algorithm and grey wolf optimizer algorithm. A set of experiments are conducted on the use of developed algorithms and analysis of the obtained results is given.

The problem of scheduling work for an iteration in Scrum methodology is considered. It is considered as an optimal scheduling problem for machines with different unrelated productivity. The main characteristics of the problem include the existence of a common due date for all the machines, different unrelated productivity of the machines, the partial strict ordering set for the tasks and the value set for each of the tasks to be scheduled. The semantic and formal models of the problem are specified. A heuristic algorithm to solve the considered problem is suggested. It is based on the idea of splitting the problem into two different subproblems. For each of the resulting subproblems a formal model is specified. A greedy algorithm for finding a feasible solution is suggested for one of the subproblems.

The basic methods of analysis and forecasting of time series are considered. The effectiveness of the method of autoregression, the model of autoregressive integrated moving average (ARIMA), the method of singular spectrum analysis (SSA) and methods using neural networks based on deep learning for forecasting of time series was investigated. The effectiveness was studied on the example of the values of the function of the sinusoid, the minimum daily temperature, the market index S&P 500 and the daily number of passengers of the airline on the criterion of the lowest mean square error. A comparative analysis of the obtained results is carried out and the feasibility of using these methods is substantiated.

The state and basic possibilities of using special economic knowledge and involvement of a judicial expert in the legal systems of Europe, Australia and the USA are substantiated. In the European Network of Forensic Institutions (ENFSI) there are no issues of economic offenses. The problem of the use of special economic knowledge for the purpose of providing mutual legal assistance and international cooperation in the process of disclosing and investigating economic offenses is studied, and the necessary condition for effective detection and investigation of economic offenses is a deep knowledge. The necessity of establishing an institute of forensic economic expertise is proposed. The possibilities of international cooperation of the use of special economic knowledge, their problems and subjects, criteria of evaluation are determined.

In the article, the authors emphasize the existence of the problem of Internet addiction in the modern student environment. The phenomenon of Internet addiction, its types, signs and indicators is analyzed. The method of studying Internet addiction among students was the questionnaire. As a result of the processing and interpretation of empirical data, four groups of respondents with different degrees of Internet addiction are identified. The specificity of each group is determined by a combination of the following indicators: the amount of time spent in the Internet space; the purpose of staying on the Internet; affective changes as a result of excessive stay in the network; deterioration of working / educational / household indicators due to excessive use of the Internet; changes in the process of direct communication. The results of the studies prove the relevance of the problem of Internet addiction and suggest the development of tools for prevention and reduction of the degree of Internet addiction.

The article pays attention to practical writing as a type of linguistic ability in studing Ukrainian as a foreign language. It distinguishes a dictation as an important method in teaching of writing of foreign students. The value of different types of dictations is that they enable the teacher to organize the entire group for a certain purposeful work, activate the mental activity of students, instill skills of collective, individual and independent work, which is regulated and coordinated by the teacher. Such work teaches foreign students to quickly and accurately performance of tasks, educates their will and responsibility for independent work.
