Abstract: In some examples, transmitting node instructions can include a logical node of a neural network to: receive a first node instruction, generate an output change value based on the received first node instruction, and transmit the output change value and the first node instruction to a logical edge, and the logical edge of the neural network to: receive the output change value and the first node instruction from the logical node, generate a second node instruction based on the output change value and the first node instruction, and transmit the second node instruction.

Abstract: The present software delivery system includes a computer system and a CD-ROM. The computer system includes a central processing unit communicably coupled to a CD-ROM drive, a hard drive, and a non-volatile memory. The CD-ROM contains a control module and a plurality of software modules. Each of the software modules contains one or more software products which are the software to be delivered to the user of the computer system. Each of the software modules is assigned a unique identifier (ID) such as an identification number or code. In the non-volatile memory, addresses have been designated to contain an encrypted code key which comprises a list of identification numbers corresponding to the identification numbers of the software modules.
