If a lottery system draws its numbers through computer drawings by math equations can they control it w/o num?

Question

I mean control the equtions with some other variable without manipulating the equation with numbers.

Answer 1

Theoretically, yes. 'Random' numbers on computers aren't really so, since they use some mathementical computation to produce the so-called random numbers. The way that programs approach true randomness is add in a semi-random number called a 'seed' into the computation, often taken by checking the computer's clock for the current millisecond (a value fairly certain to be totally unpredictable). If a lottery program didn't seed its random-number generation routine correctly, it would still produce random numbers, but produce the SAME random numbers every time.
