It is commonly attributed to magnus hestenes and eduard stiefel, [1][2] who programmed it on the z4, [3] and extensively researched it Barsky) is a line clipping algorithm It works by extending each line of the convex clip polygon in turn and selecting only vertices from the subject polygon that are on the visible side. Sma* or simplified memory bounded a* is a shortest path algorithm based on the a* algorithm The main advantage of sma* is that it uses a bounded memory, while the a* algorithm might need exponential memory All other characteristics of sma* are inherited from a*.
Lamport's bakery algorithm is a computer algorithm devised by computer scientist leslie lamport, as part of his long study of the formal correctness of concurrent systems, which is intended to improve the safety in the usage of shared resources among multiple threads by means of mutual exclusion.
