A common linearization of this problem is the minimization of the maximum utilization , where ∀ ( u , v ) ∈ E : U m a x ≥ U ( u , v ) {\displaystyle \forall (u,v)\in E:\,U_{max}\geq U(u,v)} In the minimum cost multi-commodity flow problem , there is a cost a ( u , v ) ⋅ f ( u , v ) {\displaystyle a(u,v)\cdot f(u,v)} for sending a flow ...

[a] Thus, a signed 32-bit integer can only represent integer values from −(2 31) to 2 31 − 1 inclusive. Consequently, if a signed 32-bit integer is used to store Unix time, the latest time that can be stored is 2 31 − 1 (2,147,483,647) seconds after epoch, which is 03:14:07 on Tuesday, 19 January 2038.

A compromise between max-min fairness and maximum throughput scheduling is proportional fairness, where the resources are divided with the goal to achieve the same cost to each user, or to minimize the maximum cost per unit that a dataflow reaches. Expensive data flows achieve lower service quality than others in proportional fairness, but do ...
