I'm trying to minimize f[{h1,h2,h3,h4}] subject to constraints that all h's lie between 0.1 and 1. Trying to use NMinimize:
NMinimize[{f[{h1, h2, h3, h4}], {h1 > 0.1, h1 <= 1.0, h2 > 0.1, 
   h2 <= 1.0, h3 > 0.1, h3 <= 1.0, h4 > 0.1, h4 <= 1.0}}, {h1, h2, h3,
   h4}]

I keep getting errors that indicate FindMinimum is attempting to call f[] with symbolic h's, not numbers. f[] will return a number if the inputs are numbers, but if they are symbols, its not going to happen. Is there a simple thing I am doing wrong?
