In general, Evolutionary Sets of Cooperating Ship Trajectories combine some of the assumptions of game theory with evolutionary programming and aim to find optimal set of cooperating trajectoriesof all ships involved in an encounter situation. In a two-ship encounter situation the method enables the operator of an on-board collision-avoidance system to predict the most probable behaviour of atarget and to plan the own manoeuvres in advance. In a multi-ship encounter the method may be used to help an operator of a VTS system to coordinate the manoeuvres of all ships. The improvement presented here is a new way of modelling some of the COLREGS rules. Due to thischange, the method is now able to find solutions, which are more compliant with COLREGS, more intuitive and consequently - safer from the navigator's point of view. The paper contains a detaileddescription of collision-avoidance operators used by the evolutionary method and simulation examples of the method's results for digital maps.
