pub struct AdjustedStringRemoval { /* private fields */ }

Expand description

Adjusted string removal ruin strategy based on “Slack Induction by String Removals for Vehicle Routing Problems” by Jan Christiaens, Greet Vanden Berghe.

Some definitions from the paper:

string is a sequence of consecutive nodes in a tour.
cardinality is the number of customers included in a string or tour.
