What Does Peterson’s Algorithm Mean?
Peterson’s algorithm is a concurrent programming algorithm developed by Gary L. Peterson in a 1981 paper. It is known as a simple algorithm when compared to others. Peterson proved the algorithm using both the 2-process case and the N-process case.
Techopedia Explains Peterson’s Algorithm
Just as in Dekker’s algorithm, turn variables (turn) and status flags (flag) are conditions or variables that are used in Peterson’s algorithm. Because of these two conditions, and because of waiting for a turn only if other flags are set, the need to clear and reset flags is avoided. After a flag is set, the turn is immediately given away when using Peterson’s algorithm.
