Optimal Design of Submarine Pipelines by a Genetic Algorithm with Embedded On-Bottom Stability Criteria
Table 1
Soft criteria and cost functions.
Soft criteria
Cost function
Interference with Level 0 and Level 1 obstacles Severity: weight factor assigned by the specialist to each level
(19)
Longitudinal declivity Activated for the nodes of the route with declivity greater than the limit
(20)
Attractor Encourage routes near regions of interest; activated whenever route does not pass into the “attractor circle.” : weight factor indicating relative importance of each attractor
