For the ML Traveller tasks I solved the following problems:

1. Project Euler 96.
2. Hackerrank

• The Missing Characters
• Predict the Missing Grade

This problem is about solving Sudoku puzzles. This problem is rather trivial if you know about constraint logic programming solvers. I picked the Numberjack python library to code my solution in. The Numberjack library lets you code the constraints in python and uses a number of efficient constraint solvers in the back to efficiently solve the problem.

Final solution

In the missing characters problem missing characters (represented by #) in words need to be predicted.

In the missing grade problem final grades for a Mathematics course taken by a student need to be predicted given grades from other courses done by that student.
