Dear all: Would anyone let me know the usage of the boost::uniform_int combined with the one argument operator() of the variate_generator? I'd like to change the maximum parameter of the distribution at every step. #include <iostream> #include <boost/random.hpp> int main( void ) { boost::variate_generator< boost::mt19937, boost::uniform_int< std::size_t > > gen( boost::mt19937( 3 ), boost::uniform_int< std::size_t >() ); for ( std::size_t i(1); i < 100; ++i ) std::cout << gen( i ) << std::endl; return 0; } The gcc aborted the compile with the following errors: /usr/include/boost/random/variate_generator.hpp: In member function `typename Distribution::result_type boost::variate_generator<Engine, Distribution>::operator()(T) [with T = unsigned int, Engine = boost::mt19937, Distribution = boost::uniform_int<size_t>]': uniform_int.cpp:9: instantiated from here /usr/include/boost/random/variate_generator.hpp:107: error: no match for call to `(boost::uniform_int<size_t>) ( boost::random::detail::pass_through_engine<boost::random::detail::pass_through_engine<boost::mt19937>
&, unsigned int&)'
