Hi James;
Here is the way I work. Slowly and step by step. Empirically coming to the solution (hopefully). That means experimentally, call me a dabbler if you like but that is what gets the cheese in numerical and computational analysis.
What does this mean to you? It means like your doctor you can not hold anything back from me. I have to know what you know. If the data you have for some reason you feel is secret then I can not assist. I need the equations you are using and hopefully the data.
I have worked on two jobs in my life that the person who hired me would not tell me what the job was for. Wished to keep everything a secret. It took ten times longer and the solution was not maximal. There is a guy in here right now who is asking me all kinds of questions about a roulette wheel. I am unable to help him any further because he is unwilling to provide the data.
I need to see and know everything about the job to have any chance of solving it. If this is impossible please let me know now.
