This may be attained by using one model to generate

Now glpsol has new option '--seed value', where value is a seed
value (any integer) used to initialize the pseudo-random number
generator in the MathProg translator. The seed value can be specified
as ? (question mark), in which case it is assigned some random
(time-based) number. If the option '--

I think it would be better to have a seed parameter passed to the
translator rather than the seed statement built into the language.
On the command-line level this could look like 'glpsol --seed 314159'.

Andrew,
Thanks. This gave me a good start, I came up with the following idea to
generate a starting point for each time the code is executed:
param utc := prod {1..2} (gmtime()-10);
param seed := utc - 10*floor(utc/10);
check sum{1..seed} Uniform01() > 0;
It would be nice to hav

Currently the seed function is not implemented. However, you may
skip some pseudo
Hi --
Within GMPL (i.e., MathProg) , is there a simple way to set the seed for
psuedo-random number generation? I'd like to
be able to randomize the starting point to stress test an example I'm
developing.
Thanks,
Jeff Kantor
