Single-handed sailing circumnavigation, as it was contained within the southern hemisphere; however, he made the first single-handed passage of the three great capes, and indeed the first successful single-handed passage of Cape Horn. With only three landfalls, Vito Dumas described the legs of his trip as the longest that had been made by a single-hander, and in the most ferocious oceans on the Earth. Organised single-handed yacht racing was pioneered by Britons "Blondie" Hasler and Francis Chichester, who conceived the idea of a single-handed race across the Atlantic Ocean. This was a revolutionary concept at the time, as the idea was thought
Single-entry single-exit Single-entry single-exit In graph theory, a single-entry single-exit (SESE) region in a given graph is an ordered edge pair ("a", "b") of distinct control flow edges "a" and "b" where: where a node "x" is said to dominate node "y" in a directed graph if every path from start to "y" includes "x". A node "x" is said to postdominate a node "y" if every path from "y" to end includes "x". So, "a" and "b" refer to the entry and exit edge, respectively. The first condition ensures that every path from start into the region passes through the region’s
