Determining the optimal course alteration manoeuvre in a multi-target encounter situation for a given ship domain model

The paper introduces a new numerical deterministic method of finding the necessary course alteration manoeuvre in a multi-target encounter situation for a given ship domain model. Its simplicity, flexibility and low computational complexity make this algorithm a useful component for real-time systems, where processing time is of importance. The algorithm is presented explicitly, so that it could be directly applied in any on-board collision avoidance system or VTS system. Example results of its use are also provided.
