Optimization II, Project 1 In this data set, there are 4 tables. Each table is a ``csv`` file. It has two columns: ``quizzes`` and ``solutions``. The entries are strings of numbers. Each string is a 81-character array. In the ``quizzes`` column, the 0s represent the empty slots in the problem, the ``solutions`` column has the correct answer in it. Inspiration There are many related research works already. This project is mostly inspired by the [1 million sudoku games](https://www.kaggle.com/bryanpark/sudoku). The large data set is from there directly, the other data sets are collected from other places. Data sets To estimate your performance and be fair to all of us. Let's use the random number seed 42 for random numbers generation. - For small datasets, you have to run all cases. Then report the success rate of your algorithms. - For large datasets, you have to uniformly randomly sample 1000 cases from each dataset. Then report the success rate of your algorithms.
