@article{Letsios2019ApproximationAF, title={Approximation Algorithms for Process Systems Engineering}, author={Dimitrios Letsios and Radu Baltean-Lugojan and Francesco Ceccon and Miten Mistry and Johannes Wiebe and Ruth Misener}, journal={ArXiv}, year={2019}, volume={abs/1909.12328} }

Designing and analyzing algorithms with provable performance guarantees enables efficient optimization problem solving in different application domains, e.g.\ communication networks, transportation, economics, and manufacturing. Despite the significant contributions of approximation algorithms in engineering, only limited and isolated works contribute from this perspective in process systems engineering. The current paper discusses three representative, NP-hard problems in process systems…
