What is it about?
The aim of this paper was to make a novel symmetry analysis in relation to the importance of optimizing the ship's trajectory and safety in situations at sea where there is a risk of collision with other ships.

Why is it important?
The algorithms presented in the article and their simulation tests confirm the thesis adopted at the beginning that it is possible to maintain the symmetry of ship control in collision situations by using the dynamic programming method to optimize it and assess the collision risk neural network in order to ensure the safety of ship traffic in accordance with the rules of COLREGs
Perspectives
In future research, further refinement of the task of maintaining safe and optimal control symmetry should be considered for both non-autonomous and autonomous surface ships, including: • Improving the accuracy of the implementation of a safe and optimal path by introducing an appropriate non-linear dynamic ship model; • Analysis of other possible optimization criteria and selection of the most adequate one; • Development of game-acting ship models that would take into account non-compliance with COLREG rules leading to accidental ship collisions; • Synthesis of ship control game algorithms; • Increasing the accuracy of navigation information sources by testing the sensitivity of safe and optimal ship control to the inaccuracy of measuring devices.
