[cilib-devel] [PATCH 2/2] Removed dependency on static randomisation.
|
From: Gary P. <gpa...@gm...> - 2009-06-12 05:10:06
|
Any randomization should be applied by providing the RNG to use. The
additional benefit is that static random state has now been removed
resulting in simplified testing.
Signed-off-by: Gary Pampara <gpa...@gm...>
