Esteve, M., Rodriguez-Sala, J.J., Lopez-Espin, J.J., Aparicio, J. (2021) «Heuristic and Backtracking algorithms for improving the performance of Efficiency Analysis Trees», IEEE Access, 9:17421–17428, 9334981

Miriam Esteve, Jesús Javier Rodríguez, Juan Aparicio (Universidad Miguel Hernández de Elche) and Joe Zhu (Foisie Business School, Worcester Polytechnic Institute)
Abstract: In the technical efficiency evaluation area, it may happen that many observations obtain a similar relative technical efficiency status, making it difficult to discriminate between them. The determination of super-efficiency has been a […]
