WebbMinsky's machine remains one of the minimal known universal Turing machines. That is, there is no known such machine which decreases one parameter without increasing the other. However, Rogozhin [6], [7] has constructed seven universal machines with the following parameters: Webbpeople to ﬁnd the smallest possible universal Turing machine, amongst them Watanabe and Minsky, a universal Turing machine of the latter was the smallest known for several years [8]. A few more little improvements in size were made through out the years but it was not until 2002 that another big dent was made in terms of size.
