Yes. Nothing better is possible for this formulae and this is documented in algorithm, some value must be excluded. Excluding 0 is bad only because srand(0) is commonly used and srand(123459876) is not. Ragarding to old formulae, the question is: what is worse, generate non-random lover bits everytime (old variant) or exclude one seed value (new variant)? Of course formulae can be changed to some another algorithm, but keep in mind that rand() must be simple and speedy. Now used variant is most simpler, others are much more complex. -- Andrey A.
