As pointed out by Edmar Hell Kampke and Maria Claudia Silva Boeres instances comp03 and comp15 in the .ctt format are identical. This is not intentional and it must have been caused by a mistake when we initially converted the files from their original formats to .ctt. We apologize for this mistake. The corresponding .ectt files are significantly different because the extended .ectt format contains extra information that has been added in a later stage in a partially-random way. In conclusions, if you solve the basic formulations UD1/UD2, you can ignore one of the two instances comp03 and comp15. If you work of formulations UD3-UD5, they are both meaningful.
