ABSTRACT
The third approach was proposed by Zappoli (1972), who treated the minimal time problem as a decision process solvable using dynamic programming. The sailing domain is discretized using grid refinement techniques. Allsopp & al. (2000), modified this method integrating branching scenario structure to model the manner the weather will evolve in time. The main advantage of that kind of method is that the problem is divided into a set of linked stages and the optimal decision depends on decisions made in the previous stages. But, for fine grid, the calculation time may be very high and the amount of data very large.
