I've read both guides ( http://commons.apache.org/proper/commons-math/userguide/optimization.html and http://commons.apache.org/proper/commons-math/userguide/leastsquares.html) regarding optimization yet I'm still unsure about how to apply those examples to my case.
What I want to do is to optimize the parameters alpha, beta and gamma in these three equations: http://www.itl.nist.gov/div898/handbook/pmc/section4/pmc435.htm I'm afraid I lack the mathematical understanding to come up with an appropriate function. I well understand the Quadratic Problem example, however, I'm kind of overwhelmed when trying to do this for my problem (as my equation has three parts). Do I need to derive the different parameters as it was done in the example? Is there a way to do that without calculating derivatives? I'd appreciate some help towards this task as I'm not making any process at the moment. I hope this is the right place to put the question. Thanks! Thom
