What does mean "5090 cache records were used,5090 cache records rejected" in MT4 Optimisation ?

[Vikram J U]

Sir,

I unmarked this "Skip Useless Results" in Optimisation Result tab.

I marked this Genetic Algorithms but I want to Mark this Genetic Algorithms because There is a lot of parameter in Input tab for My EA Robot Trading.

I checked this Journal tab in Strategy tester Optimistion .

What does mean "5090 cache records were used, 5090 cache records rejected" ?
