I started to study for my first course in the systems science certificate

I printed the course outline for SYS5130 Systems Optimization and Management. I then used the Carleton university library web journal search and found these ebooks at the Knovel Library and read this book:

Rao, Singiresu S. Engineering Optimization - Theory and Practice (3rd Edition) (John Wiley & Sons, 1996).

I type set equation 1.1 from this book in TeXshop and then stopped studying.
