While testing the max-sum algorithm against an example in a paper. I found a discrepancy between the papers value for a particular message and my codes value for a particular message. I checked the value manually on paper and it was the same as my codes. I then showed Gopal and he confirmed that the maths that I had used was sound. I am going to check that the paper has made mistake at my supervisors meeting today (just to make sure that I have implemented the max-sum algorithm correctly). TODO: Continue implementation of the max-sum algorithm, Lecture 12:00, version 2 of Gantt Chart
