I am working on a paper for a class, and I've come to somewhat of a block. I'll keep the question general. If I have three non-linear real valued functions, (1) [tex] f_1(x) [/tex] (2) [tex] f_2(x,W,H) [/tex] (3) [tex] f_3(x,W,H) [/tex] that form a function: [tex] F(x,W,H) = f_1 + f_2 + f_3 [/tex] How would I maximize [tex] F(x,W,H) [/tex]. Lagrange multipliers are ringing a bell... but before I get too invested in an idea, I would like the proper road to travel down. So If someone could point me in the right direction that would be awesome.
