Tic-tac-toe (or noughts and crosses) is a simple strategy game in which two players take turns placing a mark on a 3x3 board, attempting to make a row, column, or diagonal of three with their mark. In this homework, we will use the tools we've covered in the past two weeks to create a tic-tac-toe simulator and evaluate basic winning strategies.

Players soon discover that best play from both parties leads to a draw.

Because of the simplicity of tic-tac-toe, it is often used as a pedagogical tool for teaching the concepts of good sportsmanship and the branch of artificial intelligence that deals with the searching of game trees. It is straightforward to write a computer program to play tic-tac-toe perfectly, to enumerate the 765 essentially different positions (the state space complexity), or the 26,830 possible games up to rotations and reflections (the game tree complexity) on this space.

A cipher is a secret code for a language. In this study, we will explore a cipher that is reported by contemporary Greek historians to have been used by Julius Caesar to send secret messages to generals during times of war.

The Caesar cipher, also known as a shift cipher, is one of the simplest forms of encryption. It is a substitution cipher where each letter in the original message (called the plaintext) is replaced with a letter corresponding to a certain number of letters up or down in the alphabet.

In this way, a message that initially was quite readable, ends up in a form that can not be understood at a simple glance.

In this case study, we will find and plot the distribution of word frequencies for each translation of Hamlet. Perhaps the distribution of word frequencies of Hamlet depends on the translation.

In this case study, we will analyze a dataset consisting of an assortment of wines classified into "high quality" and "low quality", and will use k-Nearest Neighbors to predict whether or not other information about the wine helps us correctly guess whether a new wine will be of high quality.

In this case study, we have prepared step-by-step instructions for you on how to prepare plots in Bokeh, a library designed for simple and interactive plotting. We will demonstrate Bokeh by continuing the analysis of Scotch whiskies.

In this case study, we will continue taking a look at patterns of flight for each of the three birds in our dataset.

Homophily is a network characteristic. Homophily occurs when nodes that share an edge share a characteristic more often than nodes that do not share an edge. In this case study, we will investigate homophily of several characteristics of individuals connected in social networks in rural India.
