Wow !
A machine building a better machine and beating humans at this.
Edit :
is “RTL” as descibed in the answer to my comment, by @AbouBenAdhem or is it as I guessed ? :
Resistor-transistor logic ( RTL ), sometimes also known as transistor-resistor logic ( TRL ), is a class of digital circuits built using resistors as the input network and bipolar junction transistors (BJTs) as switching devices.
