The maximum stable set problem is a well-known NP-hard problem in combinatorial optimization, which can be formulated as the maximization of a quadratic square-free polynomial over the (Boolean) hypercube. We investigate a hierarchy of linear programming relaxations for this problem, based on a...

In project scheduling, a set of precedence-constrained jobs has to be scheduled so as to minimize a given objective. In resource-constrained project scheduling, the jobs additionally compete for scarce resources. Due to its universality, the latter problem has a variety of applications in...

Most research on single machine scheduling has assumed the linearity of job holding costs, which is arguably not appropriate in some applications. This motivates our study of a model for scheduling $n$ classes of stochastic jobs on a single machine, with the objective of minimizing the total...
