For the ML Traveller tasks I solved the following problems:
- Project Euler 96.
- Hackerrank
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.
In the missing characters problem missing characters (represented by #) in words need to be predicted.
IPython notebook link with description of solution.
The final file submitted to Hackerrank
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.
