C++ Reference: class PairExchangeOperator
Note: This documentation is automatically generated.
Operator which exchanges the position of two pairs; for both pairs the first
node of the pair must be before the second node on the same path.
Possible neighbors for the paths 1 -> A -> B -> 2 -> 3 and 4 -> C -> D -> 5
(where (1, 3) and (4, 5) are first and last nodes of the paths and can
therefore not be moved, and (A, B) and (C,D) are pairs of nodes):
1 -> [C] -> [D] -> 2 -> 3, 4 -> [A] -> [B] -> 5
