Description
Does WHIZARD 2 at the moment always take the same random seed? # Successive runs produce exactly the same numbers.

Fixed with changeset [1285].
By default, W2 now takes an arbitray seed (from the system clock). The command
seed = 1234 resets the seed to the specified value.
Note: See
TracTickets for help on using
tickets.
The random seed is set to zero at initialization. Setting a different seed, or using some unpredictable seed, is an option that I wanted to implement later.
