An Approximation Algorithm for a General Class of Multi-Parametric Optimization Problems
Stephan Helfrich, Arne Herzel, Stefan Ruzika +1
In a widely-studied class of multi-parametric optimization problems, the objective value of each solution is an affine function of real-valued parameters. Then, the goal is to prov…
