Soft criteriaCost function

Interference with Level 0 and Level 1 obstacles
Severity: weight factor assigned by the specialist to each level
Longitudinal declivity
Activated for the nodes of the route with declivity
greater than the limit
Encourage routes near regions of interest; activated whenever route does not pass into the “attractor circle.”  
: weight factor indicating relative importance of each attractor
