jline.opt.variables.DecisionVariable

jline.opt.variables.RoutingProbabilities

public class RoutingProbabilities
extends DecisionVariable

Optimize the routing probabilities of a job class from a source node to a list of target nodes. Uses stick-breaking encoding (dimension = targets - 1) so probabilities sum to 1. On apply, default routing is reconstructed from the connection matrix for every class (a uniform split over outgoing links, reproducing LINE's link() semantics), then the overridden (class, source) row is replaced with the decoded probabilities. Mirrors native-Python RoutingProbabilities.
