- To see 1000 spins would take a couple days of continuous play. 3) A number can stay below average for more than 1000 spins 4) If I played that kind of system I would a) use a very mild progression (ie. Increase bet if after the next 100 spins you are still in loss) and b) cover neighboring numbers, with lower unit denominations, for safety.

I doubt that you can record 10,000 spins continuously. All casinos alternate closing some tables at some point and operate with fewer tables if there are not too many players. Every roulette closes at some point every day. But the spins of the same roulette are statistically connected, even if there are interruptions.
Revisions
This assignment is subject to change up until 3 weeks prior to the due date. We do not anticipate changes; any changes will be logged in this section.
Overview
This assignment counts towards 3% of your overall grade.
The purpose of this assignment is to get you started programming in Python right away and to help provide you some initial feel for risk, probability, and 'betting.' Purchasing a stock is, after all, a bet that the stock will increase in value.
In this project, you will evaluate the actual betting strategy that Professor Balch uses at roulette when he goes to Las Vegas. Pala casino online. Here it is:
Here are some details regarding how roulette betting works: Betting on black (or red) is considered an 'even money' bet. That means that if you bet N chips and win, you keep your N chips and you win another N chips. If you bet N chips and you lose then those N chips are lost. The odds of winning or losing depend on whether you're betting at an American wheel or a European wheel. For this project we will be assuming an American wheel.

Template
Set up your development environment
First, if you haven't yet set up your software environment, follow the instructions here: ML4T_Software_Setup. This is the base directory structure used for all projects in the class, including supporting data, and the software will be set up correctly when you follow those instructions.
Then:
- Download the template code here: File:Martingale_2021Spring.zip
- Extract its contents into the base directory (ML4T_2021Spring)
- You should see the following directory structure:
- ML4T_2021Spring/: Root directory for course
- data/: Location of data
- grading/: Grading libraries used by the individual grading scripts for each assignment.
- util.py: Common utility library. This is the only allowed way to read in stock data. Only use the API methods provided here to read in stock data. Do NOT modify this file. For grading, we will use our own unmodified version.
- README.md
- martingale/: Root directory for this project
- martingale.py: Main project file to use as a template for your code.
- ML4T_2021Spring/: Root directory for course
Best Roulette Simulator
You should change only martingale.py. All of your code should be in that one file. Do not create additional files. It should always remain in and run from the directory ML4T_2021Spring/martingale/. Leave the copyright information at the top intact.
- Implement the necessary functions in martingale/martingale.py.
- To execute your martingale code for debugging purposes, run PYTHONPATH=.:. python martingale.py from the martingale/ directory.
To test your code, we will be calling __main__() function only. Doing so should run all aspects of the program and output the desired charts.
Tasks
author() and gtid() function
Revise the code functions author() and gtid() to correctly include your GT Username and 9 digit GT ID respectively. Your GT Username should be something like tbalch78 and your GTID is a 9 digit number. You should also update this information the comments section at the top.
Build a simple gambling simulator
Revise the code in martingale.py to simulate 1000 successive bets on spins of the roulette wheel using the betting scheme outlined above. You should test for the results of the betting events by making successive calls to the get_spin_result(win_prob) function. Note that you'll have to update the win_prob parameter according to the correct probability of winning. You can figure that out by thinking about how roulette works (see wikipedia link above).
Track your winnings by storing them in a numpy array. You might call that array winnings where winnings[0] should be set to 0 (just before the first spin). Winnings[1] should reflect the total winnings after the first spin and so on.
Chart Creation
Roulette Simulator With Track
For the following charts, and for all charts in this class you should use python's matplotlib library. Your submitted project should include all of the code necessary to generate the charts listed in your report. You should configure your code to write the figures to .png files. Do not allow your code to create a window that displays images (DO NOT use plt.show() and manually save as .png files). If it does you will receive a penalty.
Experiment 1: Explore the strategy and make some charts
Now we want you to run some experiments to determine how well the betting strategy works. The approach we're going to take is called Monte Carlo simulation where the idea is to run a simulator over and over again with randomized inputs and to assess the results in aggregate. Review the 'report' section below for specific properties of the strategy we want you to evaluate.
- Figure 1: Run your simple simulator 10 times and track the winnings, starting from 0 each time. Plot all 10 runs on one chart using matplotlib functions. The horizontal (X) axis should range from 0 to 300, the vertical (Y) axis should range from -256 to +100. Note that we will not be surprised if some of the plot lines are not visible because they exceed the vertical or horizontal scales.
- Figure 2: Run your simple simulator 1000 times. Remember that the simple simulator simulates 1000 successive bets, so you will be running that 1000 times. Plot the mean value of winnings for each round of spin using the same axis bounds as Figure 1. For example, you should take the mean of the first spin of all 1000 simulations. Add an additional line above and below the mean, at mean (+) standard deviation, and mean (-) standard deviation of the winnings at each point.
- Figure 3: Use the same data you used for Figure 2, but plot the median instead of the mean. Add an additional line above and below the median at median (+) standard deviation, and median (-) standard deviation of the winnings at each point.
For all of the above charts and experiments, if and when the target $80 winnings is reached, stop betting and allow the $80 value to persist from spin to spin (e.g., fill the data forward with a value of $80).
Experiment 2: A more realistic gambling simulator
You may have noticed that the strategy works pretty well, maybe better than you expected. One reason for this is that we were allowing the gambler to use an unlimited bank roll. In this experiment we're going to make things more realistic by giving the gambler a $256 bank roll. If he or she runs out of money, bzzt, that's it. Repeat the experiments above with this new condition. Note that once the player has lost all of their money (i.e., episode_winnings reaches -256) stop betting and fill that number (-256) forward. An important corner case to be sure you handle is the situation where the next bet should be $N, but you only have $M (where M
- Figure 4: Run your realistic simulator 1000 times. Plot the mean value of winnings for each spin using the same axis bounds as Figure 1. Add an additional line above and below the mean at mean (+) standard deviation, and mean (-) standard deviation of the winnings at each point.
- Figure 5: Use the same data you used for Figure 4, but plot the median instead of the mean. Add an additional line above and below the median at median (+) standard deviation, and median (-) standard deviation of the winnings at each point.
Contents of Report
Answer the following prompt in a maximum of 7 pages (excluding references) in JDF format. Any content beyond 7 pages will not be considered for a grade. Seven pages is a maximum, not a target; our recommended per-section lengths intentionally add to less than seven pages to leave you room to decide where to delve into more detail. This length is intentionally set expecting that your submission will include diagrams, drawings, pictures, etc. These should be incorporated into the body of the paper unless specifically required to be included in an appendix.
The JDF format specifies font sizes and margins, which should not be altered. Charts should be generated by the code and saved to files. Charts should be properly annotated with legible and appropriately named labels, titles, and legends.
Please address each of these points / questions in your report. The report is to be submitted as report.pdf.
