The solver will find optimized paths, through the weather systems, which respect all of the settings. This may mean the paths generated avoid areas of high wind, avoid boundary lines you have defined, and so on.
If you have a series of points you need the solver to keep to one side of the vessel or the other, they points can be described to the system as a constraint sequence.
You can set the constraint sequence you want to be respected here, or set it to none.
See the section User Manual | Constraint Sequences for details on how to create constraints.
