WebAug 27, 2024 · An improved Graham scan convex hull algorithm is designed using the convex hull region shrinkage algorithm and the sample selection decision algorithm. In the sorting of Graham scan convex hull algorithm, the cross-multiplication method is used instead of the operation of finding the polar angle, which avoids the high computational … WebExamples: >>> graham_scan ( [ (9, 6), (3, 1), (0, 0), (5, 5), (5, 2), (7, 0), (3, 3), (1, 4)]) [ (0, 0), (7, 0), (9, 6), (5, 5), (1, 4)] >>> graham_scan ( [ (0, 0), (1, 0), (1, 1), (0, 1)]) [ (0, 0), (1, 0), (1, 1), (0, 1)] >>> graham_scan ( [ (0, 0), (1, 1), (2, 2), (3, 3), (-1, 2)]) [ (0, 0), (1, 1), (2, 2), (3, 3), (-1, 2)] >>> graham_scan ( [ …
