Abstract

The goal of this paper is to discuss the problem of avoiding collisions at sea from the perspective of an evolutionary process and representation in this problem the risk of collision. In an evolutionary method (EP/N Evolutionary Planner Navigator System) of generating paths of the ship in partially-known environments is presented. Based on the E/PN planning concept, a modified version of the system has been developed which takes into account the specific character of the collision avoiding process. The main innovation of this modified version is the existence of different types of static and dynamic constraints, which reflect the real environment with moving strange ships (targets) and their dynamic characteristics. The evolutionary process which searches for a near- optimum trajectory in a collisi
