- By using pairing model ( (1/...), (2/, ...) ... ) what is the solution for DFS starting from zero.Describe how Lamport's approach, when used in distributed systems, keeps a global state under check.In this problem, let REF(x.i) → DEF(x.k) denote that the linker willassociate an arbitrary reference to symbol x in module i to thedefinition of x in module k . For each example below, use thisnotation to indicate how the linker would resolve references to themultiply-defined symbol in each module. If there is a link-time error(rule 1), write " ERROR ". If the linker arbitrarily chooses one of thedefinitions (rule 3), write " UNKNOWN ".A./* Module 1 */ /* Module 2 */int main() static int main=1[{ int p2()} {}(a) REF(main.1) → DEF(_____._____)(b) REF(main.2) → DEF(_____._____)B./* Module 1 */ /* Module 2 */int x; double x;void main() int p2(){ {} }(a) REF(x.1) → DEF(_____._____)(b) REF(x.2) → DEF(_____._____)C./* Module 1 */ /* Module 2 */int x=1; double x=1.0;void main() int p2(){ {} }(a) REF(x.1) → DEF(_____._____)(b) REF(x.2) → DEF(_____._____)
- Correct answer will be upvoted else downvoted. Computer science. It might have been a simple undertaking, yet it worked out that you ought to observe a few guidelines: Before all else, you select any sure integer x. Then, at that point, you do the accompanying activity n times: select two components of cluster with total equivalents x; eliminate them from an and supplant x with limit of that two numbers. For instance, if at first a=[3,5,1,2], you can choose x=6. Then, at that point, you can choose the second and the third components of a with total 5+1=6 and toss them out. After this activity, x equivalents 5 and there are two components in cluster: 3 and 2. You can toss them out on the following activity. Note, that you pick x before the beginning and can't transform it as you need between the activities. Decide how could you act to toss out all components of a. Input The main line contains a solitary integer t (1≤t≤1000) — the number of experiments.…Use the standard process we saw in class to derive an NFA from the RE ((a∗bc)∗)∗, and then use the subset algorithm to give an equivalent DFA. Either formalizing the DFA/NFA or diagramming them clearly will be sufficient. The final DFA should be labled with sets of NFA states.We use AdaBoost to perform classification on 5 objects (1) If first classifier f, classifies 2 objects incorrectly (classification error = 0.4). What weight should be assigned to objects that were classified correctly and incorrectly, respectively, such that, under the new weights, the performance of fi would be the same as random (classification error = 0.5). (2) Next, choose a second classifier f2, what is the classification error? What is the new weight? (3) Find a third classifier f3, what is the classification error? What is the new weight? (4) Combine the three classifiers using AdaBoost. What is the final classifier H(x)? What is the final error rate?
- Implement the rumor mongering dissemination model in gossip-based data propagation. Pick at least 5 processes and implement one probability model in any language of your choice. You can implement the processes as an array or however you would like.Correct answer will be upvoted else downvoted. Computer science. You are putting away an integer cluster of length m in an information base. To keep up with interior trustworthiness and secure information, the data set stores n duplicates of this cluster. Shockingly, the new episode might have modified the put away data in each duplicate in the data set. It's accepted, that the occurrence adjusted all things considered two components in each duplicate. You wanted to recuperate the first exhibit dependent on the present status of the data set. On the off chance that there are different ways of reestablishing the cluster, report any. In case there is no cluster that contrasts from each duplicate in close to two positions, report that too. Input The main line contains integers n and m (2≤n; 1≤m; n⋅m≤250000) — the number of duplicates and the size of the exhibit. Every one of the accompanying n lines portrays one of the at present put away duplicates in the information…A dispatcher of RTOS has the following three resources, A, B, and C. A has 7 instances, B has 5 instances, and C has 6 instances. At this time, the allocation, request and available map is shown in table Q1 below. a. Is this system in a safe state? Execute necessary algorithm to show your result. b. Is there a valid sequence that can work for this map? If so show it and state if it is the only one or not. c. Given the allocation table below, if PO requests 1 more resource from A and it is granted, will the system be in a safe state? d.

- Computer Science Use UML to model the following scenario: A water purification plant is identified by its name and alphanumeric plant ID. The name of the plant can change but its ID cannot. Each plant purifies water but has a number of purification mechanisms for doing so. Conventional Filtration, Evaporation, Flocculation and Nano Filtration are each different kinds of filtration mechanism that implement the filter behaviour differently. Each filtration mechanism has an associated cost which can be accessed but not modified.ll businesses want to keep their customers happy. To do that, many companies assign a certain amount of time to each customer to optimize the business. The alternative would be to hire more employees, which would lead to higher costs. This problem requires you to simulate how authorities optimize the number of cashiers at the entrance of a toll bridge to make sure drivers are satisfied. Make the following assumptions: There is one cashier per line. The line works as a queue with no cars cutting the line or leaving it. One car arrives at the entrance every 10 seconds. It takes 90 seconds (1.5 minutes) to process the payment, starting from the moment a cashier is available. Assume there is no pause between cars. Your Tasks: Design class CarInLine, with the following specifications: The class has two instance variables: arrivalTime and DepartureTime, stored as integers. Define a constructor that accepts an integer as an argument representing the arrival time, in which you set the…Part(a): What is a Deadlock? How it is detected?
