On the Min-Max-Delay Problem: NP-completeness, Algorithm, and Int-Gap

  title={On the Min-Max-Delay Problem: NP-completeness, Algorithm, and Int-Gap},
  author={Qingyu Liu and Lei Deng and Haibo Zeng and Minghua Chen},
We study a delay-sensitive information flow problem where a source streams information to a sink over a directed graph G(V,E) at a fixed rate R possibly using multiple paths to minimize the maximum end-to-end delay, denoted as the Min-Max-Delay problem. Transmission over an edge incurs a constant delay within the capacity. We prove that Min-Max-Delay is weakly NP-complete, and demonstrate that it becomes strongly NP-complete if we require integer flow solution. We propose an optimal pseudo…

On the min-max-delay problem: NP-completeness, algorithm, and integrality gap

It is proved that Min-Max-Delay is weakly NP-complete, and it is demonstrated that it becomes stronglyNP-complete if the authors require integer flow solution, and an optimal pseudo-polynomial time algorithm is proposed.



On the Quickest Flow Problem in Dynamic Networks - A Parametric Min-Cost Flow Approach

This result shows for the first time that the quickest flow problem can be solved within the same time bound as one of the fastest algorithms for the min-cost flow problem.

Fast, Fair, and Efficient Flows in Networks

It is shown that an s-t-flow that is optimal with respect to the average latency objective is near-optimal for the maximum latency objective, and it is close to being fair.

Max Flow and Min Cut with bounded-length paths: complexity, algorithms, and approximation

A primal–dual approximation algorithm is given for both problems whose approximation ratio attains the integrality gap, thereby showing that it is the best possible primal– dual approximation algorithm.

A new algorithm for solving linear programs that requires only Õ(√rank(A)L) iterations where A is the constraint matrix of a linear program with m constraints, n variables, and bit complexity L is presented.

Traffic Assignment with Maximum Delay Constraint in Stochastic Network

This work looks into the traffic assignment problem in the stochastic network, considering the maximum delay constraint, and forms the Stochastic Delay Constrained Maximum Flow problem (SDCMF), and proves that it is NP- Complete.

A network, in which two integers tij the traversal time and cij the capacity are associated with each arc PiPj, is considered with respect to the following question. What is the maximal amount of

Sending Perishable Information: Coding Improves Delay-Constrained Throughput Even for Single Unicast

The first example showing that network coding can achieve strictly higher delay-constrained throughput than routing even for the single unicast setting is presented, and the NC gain can be arbitrarily close to 2 in some instances.
