Struct vrp_core::solver::mutation::AdjustedStringRemoval[−][src]

pub struct AdjustedStringRemoval { /* fields omitted */ }
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.
