Minimum area polygons with two reflex angles enclosing k Points Autor Krithivasan, Kamala, Srilakshmi, Vanam

“… We also analyse the complexities of each of the algorithms. We find that out of the four orthogonal polygons with two reflex angles, three are orthoconvex and the algorithms presented for these polygons work in time, where n could be O(n-k…”
