question: can this tool be used to evaluate my own list of numbers

[gmmoura]

Hi,

(This is more of a question than I issue. )
Suppose I have a txt file with millions of numbers obtained from real-data measurements.

Can I use your tool to run the battery test and evaluate the randomness of these numbers ?
They range from 0 to 2^16.

If so, is there an example I could use to do that?

Thanks

I'm guessing this package is basically abandonware. I have the same question and the supposed "User Guide" gives no useful information.

void bbattery_SmallCrushFile (char *filename);

so it may be possible to supply your sequence in a file name. That seems to be your case, so "all you need to do" is figure out how that file is parsed. As ascii or binary, what format, ....

I was looking for an integation like this:

void bbattery_SmallCrush (unif01_Gen *gen);

where

typedef struct {
   void *state;
   void *param;
   char *name;
   double (*GetU01) (void *param, void *state);
   unsigned long (*GetBits) (void *param, void *state);
   void (*Write) (void *state);
} unif01_Gen;

is some spec for a random number generator. So you could wrap your own in this struct.

Victor (and others): See the module "ufile", on page 86 of the short user guide.  This is where the generators defined by reading numbers from a file are implemented.  We use ufile_CreateReadText to read uniform random numbers over [0,1], which must be in an ASCII file in text format, with white spaces between the numbers. We use ufile_CreateReadBin to read binary files which contain only a sequence of bits, with no space. The Crush batteries use the former, because they are designed to test sequence of U(0,1) random numbers in floating point.   The Rabbit and Alphabit batteries are designed to test binary sequences, so they use the latter format.  I think this is all said in Chapter 4 of the guide.

-------------------------------- Of course, you can also create your own gen as an instance of the struct, as done in the several u* files, and this gen can do whatever you want.  You can look at the u*.c files, including ufile.c.
