A comment on performance guarantees of a greedy algorithm for minimizing a supermodular set function on comatroid
Orçun Karaca, Baiwei Guo, Maryam Kamgarpour · European Journal of Operational Research · 2020
We provide a counterexample to the performance guarantee obtained in the paper “Il’ev, V., Linker, N., 2006. Performance guarantees of a greedy algorithm for minimizing a supermodular set function on comatroid”, which was published in Volume 171 of the European Journal of Operational Research. We point out where this error originates from in the proof of the main theorem.
