'''Huang's algorithm''' is an [[algorithm]] for detecting [[Termination analysis|termination]] in a [[distributed system]]. The algorithm was proposed by [[Shing-Tsaan Huang]] in 1989 in the ''[[JournalInformation ofProcessing ComputersLetters]]''.<ref>{{cite journal |last1=Huang |first1=Shing-Tsaan |author1-link=Shing-Tsaan Huang |title=Termination detection by using distributed snapshots |journal=Information Processing Letters |volume=32 |issue=3 |pages=113–119 |year=1989 |url=https://www.sciencedirect.com/science/article/abs/pii/0020019089900100 |doi=10.1016/0020-0190(89)90010-0 |url-access=subscription }}</ref>

==Termination detection==

The basis of termination detection is in the concept of a distributed system process' state. At any time, a process in a distributed system is either in an active state or in an idle state. An active process may become idle at any time but an idle process may only become active again upon receiving a computational message.

Termination occurs when all processes in the distributed system become idle and there are no computational messages in transit.
