GA Application for Software Testing

Referring to my last post: (https://www.freelancer.com/projects/Matlab-Mathematica/Deriving-Fitness-Function-for-search/), I managed to derive three fitness functions which indicates finishing the 1st phase. However, I 'am baffled on which one is the most suitable for my data sets. The bottom line is maintaining the states coverage while minimizing the sequences of operations and, consequently, reducing testing time. I need a freelancer who can develop the DESKTOP application for me that takes these files as input by user and apply GA with its fitness function along with the operators (selection, crossover and mutation). There is no preference in terms of the programming language but MATLAB is most likely. If you are interested, please contact me for further discussions.
