Alex., Some time ago I was involved with this topic (for steel parts). I was told by experts in the area that skilled manual arrangers can often beat computer algorithms because the manual arranger knows that certain edges can tolerate a small amount of interference where other edges must be left pristine. There might be a real opportunity for developing a hybrid manual/auto visual approach. If thats the case, you don't need a super good algorithm, but speed would be important. Richard Hill
