std::set< nat_type > | mpi::mpi_check_gentle_varsigma_odd__dynamic (nat_type first_n, nat_type last_n, const std::set< nat_type > &previous_bad_table=std::set< nat_type >(), bool print_bad=true, unsigned int range_size=20000, unsigned int master_range_size=200) |
Check in the order all odd gentle numbers between first_n and last_n, and if print_bad then print all bad numbers between first_n and last_n (included). The consequence of the result is that: if (all numbers < first_n respect the conjecture) and (all perfect squares < last_n respect the conjecture) and (all bad numbers < last_n respect the conjecture) then all numbers < last_n respect the conjecture.
