Convex geometry | Optimization algorithms and methods
Dykstra's algorithm is a method that computes a point in the intersection of convex sets, and is a variant of the alternating projection method (also called the projections onto convex sets method). In its simplest form, the method finds a point in the intersection of two convex sets by iteratively projecting onto each of the convex set; it differs from the alternating projection method in that there are intermediate steps. A parallel version of the algorithm was developed by Gaffke and Mathar. The method is named after Richard L. Dykstra who proposed it in the 1980s. A key difference between Dykstra's algorithm and the standard alternating projection method occurs when there is more than one point in the intersection of the two sets. In this case, the alternating projection method gives some arbitrary point in this intersection, whereas Dykstra's algorithm gives a specific point: the projection of r onto the intersection, where r is the initial point used in the algorithm, (Wikipedia).

How Dijkstra's Algorithm Works
Dijkstra's Algorithm allows us to find the shortest path between two vertices in a graph. Here, we explore the intuition behind the algorithm — what information we need to keep track of, in what order we need to explore vertices, and what the limitations of the algorithm are. *** Spannin
