To give a value representing an estimate of the distance to the goal node
In the context of heuristic search, when is it more likely that node m is an optimal path to node n?
$f(m) < f(n)$
Which search algorithm requires a heuristic function?
A* search
What does 'Cost: g(n) Distance to the Goal: h(n)' represent in the given context?
The cost of reaching a node and its distance from the goal node
What does the sum 140+80+146+138+101=605 represent?
The total cost of reaching multiple nodes
What is the purpose of simulated annealing in the context provided?
To minimize the increase in heuristic values during search
What is the main purpose of an operating system?
To simplify the complexity of computer systems
Which component is responsible for the execution of user programs and operation of I/O devices?
Control program
What is a key goal of an operating system?
To keep user programs isolated and secure
Which system is characterized by running multiple programs using interrupts and securing memory and I/O devices for each program?
Multiprogramming system
What type of system is defined as a single-user, portable system with I/O devices such as laptops?
Personal computing system
Which type of parallel system is characterized by more than one CPU, providing high throughput and reliability?
Symmetric parallel system
What is the purpose of the interrupt service routine in an operating system?
To manage and deal with interrupts
In the context of CPU protection, what is the function of the dual mode (user mode - kernel mode)?
To ensure that the operating system maintains control
What is the primary role of the CPU scheduler in an operating system?
To select the next process to execute from memory
What does the term 'burst cycle' refer to in the context of process execution?
The combination of CPU execution and I/O wait during process execution
What is the main objective of non-pre-emptive scheduling in an operating system?
To complete the execution of a process once started
What is the significance of turnaround time in the context of process execution in an operating system?
It indicates the total time taken to execute a whole process
What does the base register represent in terms of memory protection in an operating system?
The smallest legal physical address for memory access
What is the main focus of high-level scheduling in an operating system?
Starting processes from scratch
Which component is responsible for transferring data directly between CPU and I/O devices in an operating system?
DMA (Direct Memory Access)
In an operating system, what is the primary purpose of enforcing priorities in scheduling objectives?
To give preferences to processes holding key resources
This quiz covers the concept of heuristic evaluation functions in search algorithms. It includes topics such as greedy search, A* search, IDA* search, hill climbing, and simulated annealing, all of which require heuristic functions for optimal pathfinding.
