A multiobjective, risk-aware framework is developed for optimal path planning of autonomous underwater vehicles operating in uncertain current. The uncertainty the current described terms a finite ensemble flow realizations. new optimization proposed that accounts full variability single problem whose solution may not necessarily coincide with any deterministic paths corresponding to individual...
