Detailed Description

Ruin strategy that removes a number of customers by performing a random walk
on the underlying routing solution. More precisely, starting from a randomly
selected seed visit, the walk is extended by either moving within the
same route or by jumping to a visit served by a different neighboring
route. Every active visit encountered along this random walk is made
unperformed.

◆ getNumRemovedVisits()

int com.google.ortools.constraintsolver.RandomWalkRuinStrategy.getNumRemovedVisits ( ) 
Number of visits removed during a ruin application defined on visits.
Note that pickup and delivery pairs are considered as a single entity,
i.e., the removal of a pickup (respectively delivery) causes the removal of
the associated delivery (respectively pickup) and it counts as a single
removal.

optional uint32 num_removed_visits = 7;

Returns
The numRemovedVisits.
