v 1.1: NP strings eliminated.
v 1.2: Scores available with optimum tracks left.
v 1.3: compared tracks and got new score.
v 1.4: Brute-force technique tried.
v 2.0: Worked with complete range of thresholds.
v 3.0: Errors calculated with respect to reference file.

1. Clone directory to your own machine.
2. Go to main directory location/pdi/pdi.
3. Use following command to run the program with pre-/defined threshold for sorting.
   python main.py <threshold> Eg. python main.py 75

Not defining a threshold will run the program with the threshold of 80%.
