Banker's algorithm is a resource allocation and deadlock avoidance algorithm developed by Edsger Dijkstra that tests for safety by simulating the allocation of predetermined maximum possible amounts of all resources, and then makes an "s-state" check to test for possible deadlock conditions for all other pending activities, before deciding whether allocation should be allowed to continue.
Deadlock prevention techniques and algorithms Name Coffman conditions Description Banker's algorithm: Mutual exclusion: The Banker's algorithm is a resource allocation and deadlock avoidance algorithm developed by Edsger Dijkstra. Preventing recursive locks: Mutual exclusion: This prevents a single thread from entering the same lock more than once.
Deadlock avoidance requires that the operating system be given in advance additional information concerning which resources a process will request and use during its lifetime. Deadlock avoidance algorithm analyzes each and every request by examining that there is no possibility of deadlock occurrence in the future if the requested resource is ...
The UNIX and Windows operating systems take this approach. [1] [2] Although using the ostrich algorithm is one of the methods of dealing with deadlocks, other effective methods exist such as dynamic avoidance, banker's algorithm, detection and recovery, and prevention. [3]

A wait-for graph in computer science is a directed graph used for deadlock detection in operating systems and relational database systems.. In computer science, a system that allows concurrent operation of multiple processes and locking of resources and which does not provide mechanisms to avoid or prevent deadlock must support a mechanism to detect deadlocks and an algorithm for recovering ...
Habermann's research included programming languages, operating systems, and development of large software systems. He was known for his work on inter-process communication, process synchronization and deadlock avoidance, and software verification, but particularly for the programming languages ALGOL 60, BLISS, Pascal, and Ada.
This entire article looks suspiciously similar to the explaination of Banker's algorithm in "Operating System Concepts" by Silberschatz, Galvin, and Gagne (pages 259-261 of the 7th edition). Everything from the structure of the article to most of the wording, with a few changes, is no different from this copyrighted work.
