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 does not impose any conditions as seen in prevention but, here each resource request is carefully analyzed to see whether it could be safely fulfilled without causing deadlock. Deadlock avoidance requires that the operating system be given in advance additional information concerning which resources a process will request and ...

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.
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.
The banker's algorithm is one such algorithm, although it is neither especially good nor especially practical. Recursive locks are perfectly valid tools, and so do not need to be "prevented", and in any case have nothing to do with the deadlock issue: like any lock, they merely ensure that competing processes do not corrupt one another's data.
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 ...
