For the following problem, decide if the provided answer correctly solves the problem. If it does then analyze the running time of the algorithm. If it does not, give an example demonstrating why not.
Problem: Given n people, n jobs, and a table of distinct "rewards" for assigning people to jobs - i.e. is the reward for assigning a person to a job; find the maximum total reward that can be achieved by a matching of people to jobs (i.e. exactly one person per job).
Solution: Use the table of rewards to set up a preference relation - e.g. Person i prefers job j1to j2 if R(i,j1) > R(i,j2); and job j prefers to be assigned to person i1 over i2 if R(i1,j)> R(i2,j) . Run the Gale-Shapley algorithm to find a matching. Compute the reward for this matching. This will be the maximum reward.

Answers

Answer 1

The provided solution correctly solves the problem by using the Gale-Shapley algorithm to find a matching between people and jobs based on their preferences. The preference relation is established using the table of rewards, where individuals prefer jobs with higher rewards and jobs prefer individuals with higher rewards.

The Gale-Shapley algorithm guarantees finding a stable matching, where there is no pair of individuals and jobs that both prefer each other over their current assignments. In this case, the algorithm will find a matching that maximizes the total reward since it considers the preferences of both individuals and jobs.

Analyzing the running time of the algorithm, the Gale-Shapley algorithm has a worst-case time complexity of \(O(n^2)\), where n is the number of people or jobs. This is because each person and each job can potentially be compared to every other person and job in the worst case.

Therefore, the provided solution correctly solves the problem and the running time of the algorithm is \(O(n^2).\)

E-business differs from traditional business in that Group of answer choices the latter caters to business-to-business deals, which do not include direct selling. the former carriers out the goals of business through the use of the Internet. the latter used the push strategy. the latter uses the pull strategy. the former permits guerilla marketing.

Answers

E-business is a form of business that leverages the internet and digital technologies to conduct commercial transactions, promote products and services, and facilitate communication between customers and businesses.

One of the key differences between e-business and traditional business models is the way in which selling is conducted. While traditional business models typically cater to business-to-business deals that do not involve direct selling, e-businesses are built around the concept of direct selling to customers through digital channels.
In e-business, selling can take on a variety of forms, including e-commerce platforms, social media marketing, email marketing, and other digital marketing tactics. This is made possible through the use of the internet, which allows businesses to reach customers from all over the world and offer them a seamless and convenient shopping experience.
Another important aspect of e-business is the ability to use guerilla marketing tactics, which are often more cost-effective and targeted than traditional advertising methods. This includes strategies such as search engine optimization, content marketing, and influencer marketing, all of which can help businesses reach their target audience in new and creative ways.

Overall, e-business represents a significant departure from traditional business models, as it allows businesses to leverage the power of the internet to reach customers and sell products in ways that were previously impossible. As technology continues to evolve, it is likely that e-business will continue to play an increasingly important role in the global economy.

True: In 32-bit mode, LOOPNZ jumps to a label when ECX is greater than zero and the Zero flag is clear.

LOOPNZ decrements the CX or ECX register by one and then jumps to the goal if CX or ECX is greater than zero and the Zero flag is not set by the most recent comparison or logical instruction. If ECX is zero, the jump does not happen, and the loop is terminated.

The basic structure of the loop is as follows: loopnz LABEL1; where LABEL1 is the label that the instruction will jump to if the Zero flag is not set and ECX is not zero.

B Ill only C I and II only D II and III only
E I,II, and III

Answers

The expression that evaluates to 3.5 is option A, I only.

To understand why, we need to follow the order of operations. In option I, we first divide 2 by 4, which gives us 0.5. Then we double that, which gives us 1. Finally, we add 3 to 1, which gives us 4. Option II first divides 2 by 4, which again gives us 0.5.

However, before doubling that, we add 3 to it, which gives us 3.5 when we finally double it. Option III looks similar to II, but we have to remember that division comes before addition, so we first add 2/4 and 3, which gives us 3.5. Then we double that, which gives us 7.

An android user recently cracked their screen and had it replaced. If they are in a dark room, the phone works fine. If the user enters a room with normal lights on, then the phone's display is dim and hard to read. What is most likely the problem?

Answers

There are two possibilities for the problem in the given scenario. The first and most probable cause of the problem is that the replaced screen was of low quality or did not meet the device's standards.

Therefore, the screen is not transmitting light properly and is producing dim or blurry images.The second possibility for the problem is that the light sensor of the phone might be affected by the screen replacement. The phone might be adjusting the brightness levels based on the low light environment in the dark room and not adjusting correctly in the normal light environment.

This can result in the phone being too bright or too dim, making it difficult to read the display.However, both of these possibilities can be avoided by purchasing a high-quality replacement screen or seeking professional assistance to fix the problem. In such cases, it is recommended to have an expert inspect the device for any faults and repair it accordingly.Moreover, one can also try to adjust the screen brightness levels manually to make the display more readable in the normal light environment.

Suppose that each stage requires 5. 3 nanoseconds to complete its task.

How many nanoseconds will it take to complete 120. 0 instructions with pipelining? Round your answer to the nearest integer

Answers

It will take approximately 655 nanoseconds to complete 120 instructions with pipelining.

Understanding Pipelining

The time to complete one instruction is the time required for one stage

1 instruction = 5.3 nanoseconds

With pipelining, multiple instructions can be in different stages of execution at the same time, so the throughput of the pipeline is higher than executing instructions one at a time.

The speedup achieved by pipelining depends on the depth of the pipeline, which is the number of stages in the pipeline. Let's assume a pipeline depth of 5 stages.

In a perfect pipeline, the time to complete N instructions is:

time = t_pipeline + (N - 1) * t_stage

where t_pipeline is the overhead of the pipeline setup and t_stage is the time required for one stage.

For a pipeline depth of 5 stages, the pipeline overhead is the time required for 4 stage transitions, which is 4 * t_stage = 4 * 5.3 = 21.2 nanoseconds.

Plugging in the values, we get:

time = 21.2 + (120 - 1) * 5.3

time = 21.2 + 633.9

time = 655.1 nanoseconds

Rounding to the nearest integer, we get:

time ≈ 655 nanoseconds
