Efficient and targeted COVID-19 border testing via reinforcement learning

Research published in Nature presents a machine learning algorithm called 'Eva' to limit the influx of tourists infected with SARS-CoV-2 into Greece. The use of the algorithm significantly increased the effectiveness of the detection of asymptomatic travellers and contributed to Greece's ability to maintain its borders safely.
