In some cases, information warfare results in almost whole population accepting one of two contesting points of view and rejecting the other. In other cases, however, the “majority party” gets only a small advantage over the “minority party”. The relevant question is which network characteristics of a population contribute to the minority being able to maintain some significant numbers. Given that some societies are more connected than others, in the sense that they have a higher density of social ties, this question is specified as follows: how does the density of social ties affect the chances of a minority to maintain a significant number? Does a higher density contribute to a landslide victory of majority, or to resistance of minority? To address this issue, we consider information warfare between two parties, called the Left and the Right, in the population, which is represented as a network, the nodes of which are individuals, and the connections correspond to their acquaintance and describe mutual influence. At each of the discrete points in time, each individual decides which party to support based on their attitude, i. e. predisposition to the Left or Right party and taking into account the influence of his network ties. The influence means here that each tie sends a cue with a certain probability to the individual in question in favor of the party that themselves currently support. If the tie switches their party affiliation, they begin to agitate the individual in question for their “new” party. Such processes create dynamics, i. e. the process of changing the partisanship of individuals. The duration of the warfare is exogenously set, with the final time point roughly associated with the election day. The described model is numerically implemented on a scale-free network. Numerical experiments have been carried out for various values of network density. Because of the presence of stochastic elements in the model, 200 runs were conducted for each density value, for each of which the final number of supporters of each of the parties was calculated. It is found that with higher density, the chances increase that the winner will cover almost the entire population. Conversely, low network density contributes to the chances of a minority to maintain significant numbers.

Simulation of combat and military operations is the most important scientific and practical task aimed at providing the command of quantitative bases for decision-making. The first models of combat were developed during the First World War (M. Osipov, F. Lanchester), and now they are widely used in connection with the massive introduction of automation tools. At the same time, the models of combat and war do not fully take into account the moral potentials of the parties to the conflict, which motivates and motivates the further development of models of battle and war. A probabilistic model of combat is considered, in which the parameter of combat superiority is determined through the parameter of moral (the ratio of the percentages of the losses sustained by the parties) and the parameter of technological superiority. To assess the latter, the following is taken into account: command experience (ability to organize coordinated actions), reconnaissance, fire and maneuverability capabilities of the parties and operational (combat) support capabilities. A game-based offensive-defense model has been developed, taking into account the actions of the first and second echelons (reserves) of the parties. The target function of the attackers in the model is the product of the probability of a breakthrough by the first echelon of one of the defense points by the probability of the second echelon of the counterattack repelling the reserve of the defenders. Solved the private task of managing the breakthrough of defense points and found the optimal distribution of combat units between the trains. The share of troops allocated by the parties to the second echelon (reserve) increases with an increase in the value of the aggregate combat superiority parameter of those advancing and decreases with an increase in the value of the combat superiority parameter when repelling a counterattack. When planning a battle (battles, operations) and the distribution of its troops between echelons, it is important to know not the exact number of enemy troops, but their capabilities and capabilities, as well as the degree of preparedness of the defense, which does not contradict the experience of warfare. Depending on the conditions of the situation, the goal of an offensive may be to defeat the enemy, quickly capture an important area in the depth of the enemy’s defense, minimize their losses, etc. For scaling the offensive-defense model for targets, the dependencies of the losses and the onset rate on the initial ratio of the combat potentials of the parties were found. The influence of social costs on the course and outcome of wars is taken into account. A theoretical explanation is given of a loss in a military company with a technologically weak adversary and with a goal of war that is unclear to society. To account for the influence of psychological operations and information wars on the moral potential of individuals, a model of social and information influence was used.
