New optimization techniques tackle human-AI text separation problem

Researchers have developed new optimization techniques to solve the Minimum Red--Blue Separating Set Problem (MRBSSP), a problem originating from computational geometry. The study introduces a compact Set-Cover ILP formulation, preprocessing rules, a GRASP algorithm, and two exact approaches: Logic-Based Benders Decomposition (LBBD) and a novel Branch-and-Benders-Cut (BBC) method. Experiments on random graphs show that ILP provides the best feasible solutions, LBBD offers the strongest lower bounds, and BBC most frequently certifies optimality. Additionally, the research applies these methods to an NLP task for distinguishing human- and AI-generated text, demonstrating the effectiveness of vocabulary-based graph features and optimization strategies for interpretability.
