The Iron Triangle (film) of what it means to fight for one's country. Whether they be a simple farmer's son (Ho), a French mercenary (Jacques), or a simple soldier (Keene) these three men bring to light a gray view of war which reflects that there are many sides to the war than just "good" or "evil". The Iron Triangle (film) The Iron Triangle is a 1989 film about the Vietnam War shot in Sri Lanka and directed by Eric Weston. The story is based on the diary of an unknown Viet Cong Soldier. This unique fact gives the movie a different perspective than many
Triangle-free graph is triangle-free or not. When the graph does contain a triangle, algorithms are often required to output three vertices which form a triangle in the graph. It is possible to test whether a graph with "m" edges is triangle-free in time O("m"). Another approach is to find the trace of "A", where "A" is the adjacency matrix of the graph. The trace is zero if and only if the graph is triangle-free. For dense graphs, it is more efficient to use this simple algorithm which relies on matrix multiplication, since it gets the time complexity down to O("n"), where "n"
