The project titled ROAD CONSTRUCTION USING HIGHWAY PLANNING AND OBSTRUCTION PREVENTION aims to address one of the major issues that the Indian road construction department is facing. Consider the 'dining philosophers' problem: n philosophers are sitting around a table, wanting to eat. Deadlock occurs when a system is unable to make progress because threads are blocking each other. Ī v a i l a b l e = A v a i l a b l e − R e q u e s t = ( 0, 0, 0, 0 ) ⇒ Available = Available-Request = (0,0,0,0) \Rightarrow A v ai l ab l e = A v ai l ab l e − R e q u es t = ( 0, 0, 0, 0 ) ⇒ unsafe ⇒ R e q u e s t \Rightarrow Request ⇒ R e q u es t can't be granted immediately. deadlock avoidance: bankers algorithm key terms: safe state Deadlock. R e q u es t = ( 2, 2, 2, 4 ) ≤ N ee d A N D R e q u es t = ( 2, 2, 2, 4 ) ≤ A v ai l ab l e. Request = (2,2,2,4) \leq Need AND Request = (2,2,2,4) \leq Available. 2023 Operating System: Bankers Deadlock Avoidance Algorithm (Hardcoded) Implementation in Python (Using Numpy aka Numerical Python) python numpy os. R e q u e s t = ( 2, 2, 2, 4 ) ≤ N e e d A N D R e q u e s t = ( 2, 2, 2, 4 ) ≤ A v a i l a b l e. ![]() This sequence of thread satisfies the safety criteria. The reason behind the name ‘ banker’s algorithm ’ is that it is mostly used in banking systems. How deadlock can be avoided using Bankers Algorithm. ![]()
