Center node: "a parameterized complexity view on non preemptively scheduling interval constrained jobs few machines small looseness and small slack"
  Abstract: We study the problem of non-preemptively scheduling n jobs, each job j with a release time $$t_j$$tj, a deadline $$d_j$$dj, and a processing time $$p_j$$pj, on m parallel identical machines. Cieliebak et al. (2004) considered the two constraints $$|d_j-t_j|\le \lambda {}p_j$$|dj-tj|≤źpj and $$|d_j-t_j|\le p_j +\sigma $$|dj-tj|≤pj+ź and showed the problem to be NP-hard for any $$\lambda >1$$ź>1 and for any $$\sigma \ge 2$$źź2. We complement their results by parameterized complexity studies: we show that, for any $$\lambda >1$$ź>1, the problem remains weakly NP-hard even for $$m=2$$m=2 and strongly W[1]-hard parameterized by m. We present a pseudo-polynomial-time algorithm for constant m and $$\lambda $$ź and a fixed-parameter tractability result for the parameter m combined with $$\sigma $$ź.
