Andrew S. Tanenbaum (OS) Edition 4 Exercise 6 Question 41 (Page No. 470)
Program a simulation of the banker’s algorithm. Your program should cycle through each of the bank clients asking for a request and evaluating whether it is safe or unsafe. Output a log of requests and decisions to a file.

Banker Algo(ACE)
Banker algorithm is used by OS to avoid the deadlock. Following table shows the current allocation and maximum demand by process $P_{1}$,$P_{2}$,$P_{3}$ and $P_{4}$ for the instances $A,B,C$ Process Max Demand (A,B,C) Current Allocation(A,B,C) $P_{1}$ ... of $A,B,C$ respectively Req2: $P_{4}$ requests $1,0,1$ of $A,B,C$ respectively Which of these two requests will be granted?

ISI2017-PCB-CS-5(a)
An operating system contains three resource classes. The number of resource units in these classes are $7, 7\ \text{and} \ 10$ ... safe? Justify. If process $P_1$ now requests $(1,1,0)$ resources, then what will be the status of the new state?

Test by Bikram | Mock GATE | Test 2 | Question: 2
Which of the following statements is NOT true? Deadlock can never occur if all resources can be shared by competing processes. Deadlock can never occur if resources must be requested in the same order by processes ... then deadlock has certainly occurred. The Banker's algorithm for avoiding deadlock requires knowing resource requirements in advance

UGC NET CSE | June 2013 | Part 3 | Question: 61
An operating system using banker’s algorithm for deadlock avoidance has ten dedicated devices (of same type) and has three processes P1, P2 and P3 with maximum resource requirements of 4, 5 and 8 respectively. There are two states of ... safe and State 2 is unsafe Both State 1 and State 2 are safe Both State 1 and State 2 are unsafe

deadlock
It the Resource-Allocation Graph contains $'m'$ types of resource and $'n'$ processes, then the time complexity of the algorithm for deciding whether the system is safe or unsafe is $O(n^2 \times m)$ $O(n \times m)$ $O(n^2 \times m^2)$ $O(n \times m^2)$
