ABSTRACT
In this paper we study the problem of scheduling wireless links in the geometric SINR model, which explicitly uses the fact that nodes are distributed in the Euclidean plane. We present the first NP-completeness proofs in such a model. In particular, we prove two problems to be NP-complete: Scheduling and One-Shot Scheduling. The first problem consists in finding a minimum-length schedule for a given set of links. The second problem receives a weighted set of links as input and consists in finding a maximum-weight subset of links to be scheduled simultaneously in one shot. In addition to the complexity proofs, we devise an approximation algorithm for each problem.

Maximizing the weighted number of just-in-time jobs in flow shop scheduling
In this paper we consider the maximization of the weighted number of just-in-time jobs that should be completed exactly on their due dates in n -job, m -machine flow shop problems. We show that a two-machine flow shop problem is NP-complete. When job ...
Approximation algorithms for minimizing the total weighted tardiness on a single machine
Given a single machine and a set of jobs with due dates, the classical NP-hard problem of scheduling to minimize total tardiness is a well-understood one. Lawler gave a fully polynomial-time approximation scheme (FPTAS) for it some 20 years ago. If the ...
