You Are Asked To Design An Algorithm To Optimize Profit On A

You are asked to design an algorithm to optimize profit on a stock X. The following is how the stock has been doing for the last 10 days: Day 1: $143; Day 2: $122; Day 3: $121; Day 4: $119; Day 5: $147; Day 6: $170; Day 7: $172; Day 8: $180; Day 9: $170; Day 10: $161. Your algorithm should: a) find the lowest price to buy and the highest price to sell. b) make the buying date before the selling date. Hint: To make the algorithm more effective you may create two arrays or lists instead of one.

You are required to make at least two comments on the responses posted by your classmates with a minimum of 50 words. Make sure you design your response with your own words. Your responses to your classmates must be of substance; not just “I agree” or “Good Post.” The purpose of the responses is to convert the discussion forum into a quality academic environment through which you improve your knowledge and understanding. Read and review all assigned course materials and chapters before you start working on your assignments.

Paper For Above Instructions

In the world of stock trading, optimizing profits is a crucial objective for investors. The algorithm we will design aims to determine the best possible buy and sell points based on historical data. We will analyze the stock price data for the last 10 days and create a solution that identifies the lowest buying price prior to the highest selling price while ensuring these transactions occur on different days.

Understanding the Problem

To solve this problem, we first need to comprehend the provided stock price data:

  • Day 1: $143
  • Day 2: $122
  • Day 3: $121
  • Day 4: $119
  • Day 5: $147
  • Day 6: $170
  • Day 7: $172
  • Day 8: $180
  • Day 9: $170
  • Day 10: $161

The goal is straightforward: identify the best days to buy at a low price and sell at a high price such that the buy comes before the sell in time.

Algorithm Design

To implement this, we will:

  1. Maintain two variables: min_price to track the lowest price encountered so far, and max_profit to store the highest profit seen based on that minimum price.
  2. Iterate through each day’s price, updating min_price when a new low is found, and calculate profits if the current price is higher than min_price.
  3. Store the corresponding buy and sell days once the maximum profit is identified.

Pseudocode

The following pseudocode outlines the design of our algorithm:

function findOptimalBuySell(prices):


min_price = float('inf')


max_profit = 0


buy_day = 0


sell_day = 0


for day in range(len(prices)):


if prices[day] 

min_price = prices[day]


buy_day = day


elif prices[day] - min_price > max_profit:


max_profit = prices[day] - min_price


sell_day = day


return (buy_day, sell_day, max_profit)

Implementation

Now let's implement this algorithm in Python:

def find_optimal_buy_sell(prices):


min_price = float('inf')


max_profit = 0


buy_day = 0


sell_day = 0


for day in range(len(prices)):


if prices[day] 

min_price = prices[day]


buy_day = day


elif prices[day] - min_price > max_profit:


max_profit = prices[day] - min_price


sell_day = day


return (buy_day, sell_day, max_profit)


Stock prices for the last 10 days


prices = [143, 122, 121, 119, 147, 170, 172, 180, 170, 161]


buy_day, sell_day, profit = find_optimal_buy_sell(prices)


print(f'Buy on day {buy_day + 1} and sell on day {sell_day + 1} for a profit of ${profit}.')

Analysis of Results

When we run the above code, we find the optimal days to buy and sell the stock. The output tells us on which day to buy and on which day to sell, enabling us to optimize our profit from this stock investment.

For the given prices, the algorithm correctly identifies the days that yield the best profit. The critical aspect of this algorithm is its linear time complexity of O(n), making it efficient for any reasonable input size. By tracking the minimum price seen at each step, it avoids the need to search through the array multiple times.

Class Interaction

Beyond the algorithmic design, interacting with classmates is an essential part of the learning process. Engaging with peers by providing substantive feedback or insightful comments improves our understanding of the topic. Aiming for quality interaction fosters a productive academic environment where knowledge can be shared and tested.

Conclusion

Designing an algorithm to optimize profit on a stock can be approached systematically by analyzing historical data. By implementing a simple and efficient algorithm, we can find the best buying and selling points based on past prices. Additionally, contributing to class discussions enhances learning, making the educational experience richer.
