Randomization function was created by gorp
Hi,
Could someone please describe to me how the randomisation function works in Limesurvey. For research purposes I would like to know the kind of randomisation that is carried out.

Any help and suggestions are greatly appreciated.

Till someone from the developers might post here, you can take a look at sections of the PHP code.

The shuffle algorithm can be found here:
