Number of passes, showing in tester during optimization

 
During optimization, the number of processed passes is showing at the bottom of the Strategy Tester screen, above the horizontal bar that fills from left to the right towards completion,

e.g. 115 / 1280

means it is now calculating pass number 115 of a total of 1280 passes.

I have a situation where it shows

e.g. 115 / 1280 (6272)

What does that mean? Is it not processing all possible combinations?
 
It means that you use the genetic optimization. See "MQL4: Genetic Algorithms vs. Simple Search in the MetaTrader 4 Optimizer" target=_blank>"MQL4: Genetic Algorithms vs. Simple Search in the MetaTrader 4 Optimizer"</a> and <a href=""MQL4: Genetic Algorithms: Mathematics"


Perfect - thank you!
 
well - i am running optimizations on two instances of MT4, installed in different directories.

i load the same set file with identical parameter ranges for optimizations... and one MT4 gives me:

e.g. 115 / 1280

while the other gives me

e.g. 115 / 1280 (6272)

same parameters to be optimized in same steps and same range, both with IBFX, version 4 build 211, released (15 Oct 2007), same data range.

needless to say that this somewhat shatters my faith in the optimization process.

does anyone have any ideas or suggestions what may be going on?
