<para>
|
|
By default igraph uses the MT19937 generator. Prior to igraph version
|
|
0.6, the generator supplied by the standard C library was used. This
|
|
means the GLIBC2 generator on GNU libc 2 systems, and maybe the BSD RAND
|
|
generator on others. The RAND generator was removed due to poor statistical
|
|
properties in version 0.10. The PCG32 generator was added in version 0.10.
