Detailed Description

The decision variables of a flat queueing network.

A DecisionVariable is a named box with a dimension and a bounded domain. The search works in a normalized [0,1] space and decode maps a point of that space onto the model quantity, so an integer variable, a rate and a probability simplex are all the same thing to the optimizer.

ServerAllocation and StationReplicas are integer counts, ServiceRate and JobPopulation continuous, RoutingProbabilities a simplex whose decode renormalizes, ClassPriority an integer ranking, and ClassServiceMapping an assignment. The layered counterparts live in layered_variables.h.
