difference between static input and input

[MohammadSaleh Haghmohammadloo]

hello guys, i wish you best.
what is actually difference between static input and normal input in MQL language? i mean 

sinput

and 

input

in the book i read written that:

"The value of a static input variable can be changed, but it cannot be optimized in the Strategy Tester. Static input variables are useful for logical grouping of input parameters."

what does it mean exactly "it cannot be optimazed"? could you tell me a example please?

It means that in can only be set when in live use or for single back-test runs, but cannot be changed in sequence during optimisations.

Normally during optimisations one can specify a start, stop and step for an input to be optimised. In this case, such a static input will remain constant and cannot be sequenced/optimised.

You quoted what it means. What part of “cannot be optimized” is unclear?
