Optimization techniques for modeling with piecewise-linear functions
Péter Dobrovoczki, Tamás Kis
In this paper we aim to construct piecewise-linear (PWL) approximations for functions of multiple variables and to build compact mixed-integer linear programming (MILP) formulation…

New complexity and approximability results for minimizing the total weighted completion time on a single machine subject to non-renewable resource constraints
Péter Györgyi, Tamás Kis
In this paper we consider single machine scheduling problems with additional non-renewable resource constraints. Examples for non-renewable resources include raw materials, energy,…
