I am obsessed with optimizing my lottery programs. What I am actually optimizing are parameters. That sort of optimization is working extremely well for Pick 3. It has not won us a Daily 4 game yet, however. For Pick 3, we have won $320 in the last ten days by playing the groups of numbers that do the best over the last 36 games. For Daily 4, we are optimizing over 24 games for some reason. I am not sure that I can justify it, but I think it is the right period. What we are optimizing is the winning amounts, give the parameters we are using. Because I am dependent on Robert Walsh's "stuff", I can't really say any more than that.
