Hi maline nadine,
I have had same problem too. I solved it this way. For
every iteration, I seeded the defaultRNG with the
random number generated in previous iteration. I hope
this will help. Here is the implementation.
#for generating random integer b/n min and max
set nextseed 0.0
proc randomNumber { min max } {
global nextseed
global defaultRNG
$defaultRNG seed $nextseed
set nRNG [new RNG]
$nRNG next-substream
set num_ [new RandomVariable/Uniform]
$num_ set min_ $min
$num_ set max_ $max
$num_ use-rng $nRNG
set nextseed [expr round([$num_ value])]
return $nextseed
}
