This file contains the main calling
routine for the Adaline (Adaptive
Linear Element) program.
Notes:
the inputs array x has N+2 elements
x[0] is always 1
then there are 1 to N elements
then the last element is the target
the weights array w has N+1 elements
w[0] is the bias
then there are 1 to N elements

Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
