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.
Algorithms that allow preemption include lock-free and wait-free algorithms and optimistic concurrency control. If a process holding some resources and requests for some another resource(s) that cannot be immediately allocated to it, the condition may be removed by releasing all the currently being held resources of that process.

Acknowledgment. The deadlock problem occurred to me for the first time when E. W. Dijkstra gave a practical solution of the problem for a special purpose [1]. Later on, I had the pleasure of discussing a general solution of the problem with him when I wrote my thesis.

An algorithm may outperform another on a problem when neither is specialized to the problem. Indeed, it may be that both algorithms are among the worst for the problem. More generally, Wolpert and Macready have developed a measure of the degree of "alignment" between an algorithm and a distribution over problems (strictly speaking, an inner ...
