public final class RandomWalkRuinStrategy
extends com.google.protobuf.GeneratedMessage
implements RandomWalkRuinStrategyOrBuilder

 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.

hasNumRemovedVisits

public boolean hasNumRemovedVisits()

 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;

Specified by:

hasNumRemovedVisits in interface RandomWalkRuinStrategyOrBuilder

Returns:

Whether the numRemovedVisits field is set.

getNumRemovedVisits

public int 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;

Specified by:

getNumRemovedVisits in interface RandomWalkRuinStrategyOrBuilder

Returns:

The numRemovedVisits.
