A deadlock avoidance algorithm dynamically examines the resource allocation state to ensure that a circular wait condition can never exist. This means that the algorithm analyzes the current allocation of resources to processes and determines if a circular wait, where each process is waiting for a resource held by another process in a circular chain, can potentially occur. If so, the algorithm takes actions to prevent the deadlock from happening, such as temporarily denying resource requests or releasing already allocated resources. By dynamically monitoring the resource allocation state, the algorithm can proactively prevent deadlocks from occurring, ensuring the smooth and efficient functioning of the operating system.
