The purpose of the study is to modify the Grey Wolf Algorithm. It is aimed at increasing the speed of the mission execution in order to examine a physical field and detect anomalies. It should consider the limitations imposed by the physical model of the group of autonomous unmanned underwater vehicles operation. For this aim, the simulator is deigned in an integrated development environment NetBeans for Java programming language. To assess the algorithm efficiency, a computational experiment was performed using several types of real physical fields as the source data. The simulation outcomes were compared to those obtained by the tack survey method. The study shows that the proposed algorithm provides better management of a group of autonomous uninhabited underwater vehicles than the wellestablished tack method of examining the physical field. The modified Grey Wolf Algorithm used in applied problems within the physical field survey proved to be beneficial and reliable. In spite of satisfactory test results, it is necessary to confirm the usage of the algorithm by real autonomous unmanned underwater vehicles. It is required to continue investigating the operation of the Grey Wolf Algorithm in a dynamically changing environment and the influence of different control functions on it. Keywords—Grey Wolf Optimizer, swarm algorithms, autonomous unmanned underwater vehicles control, autonomous unmanned underwater vehicles, optimization algorithms component.
