New algorithms tackle precedence-constrained decision trees and set cover

By PulseAugur Editorial · [1 sources] ·

Researchers have developed new approximation algorithms for optimization problems involving precedence constraints, specifically focusing on the Optimal Decision Tree and Set Cover problems. The work introduces algorithmic reductions that allow an approximation algorithm for one problem to be used for another. A key contribution is the Maximum Density Precedence-Closed Subfamily problem, which captures the combinatorial essence of the main problems. The study provides polynomial-time algorithms with $\mathcal{O}^*(\sqrt{m})$-approximation guarantees and establishes hardness results indicating $\mathcal{O}(m^{1/12-\epsilon})$-inapproximability for these problems.
