Google.OrTools.ConstraintSolver.RandomWalkRuinStrategy Class Referencesealed

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. More...

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.

◆ HasNumRemovedVisits

bool Google.OrTools.ConstraintSolver.RandomWalkRuinStrategy.HasNumRemovedVisits

◆ NumRemovedVisits

uint Google.OrTools.ConstraintSolver.RandomWalkRuinStrategy.NumRemovedVisits
getset

Number of visits removed during a ruin application defined on visits.

Note
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.
