Detailed Description

Pair-based neighborhood operators, designed to move nodes by pairs (pairs are static and given).

These neighborhoods are very useful for Pickup and Delivery problems where pickup and delivery nodes must remain on the same route. Operator which inserts pairs of inactive nodes into a path. Possible neighbors for the path 1 -> 2 -> 3 with pair (A, B) inactive (where 1 and 3 are first and last nodes of the path) are: 1 -> [A] -> [B] -> 2 -> 3 1 -> [B] -> 2 -> [A] -> 3 1 -> [A] -> 2 -> [B] -> 3 1 -> 2 -> [A] -> [B] -> 3 Note that this operator does not expicitely insert the nodes of a pair one after the other which forbids the following solutions: 1 -> [B] -> [A] -> 2 -> 3 1 -> 2 -> [B] -> [A] -> 3 which can only be obtained by inserting A after B.

inlineoverrideprotectedvirtual

Returns true if a base node has to be on the same path as the "previous" base node (base node of index base_index - 1).

Useful to limit neighborhood exploration to nodes on the same path. it's currently way more complicated to implement.

Both base nodes have to be on the same path since they represent the nodes after which unactive node pairs will be moved.
