Category: random Group: None Status: Open Resolution: None Priority: 5 Submitted By: Hubert Chan (uhoreg) Assigned to: Jens Maurer (jmaurer) Summary: uniform_01 copies engine instead of using a reference Initial Comment: In the uniform_01 class, the constructor takes a base_type (i.e. the random number generator) as its argument, and the _rng member is just a base_type. This results in uniform_01 copying the random number generator, along with its state. Thus if one creates several uniform_01 objects (e.g. one at the beginning of each of several functions), they will all return the same random numbers. The constructor should take a reference (i.e. base_type&) as its argument, and the _rng member should be a base_type&. (Indeed, the documentation at http://www.boost.org/libs/random/random-distributions.html#uniform_01 says that the constructor takes a base_type&.) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1464566&group_i... ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
