Dear Friends, I am struggling with an optimization problem and will appreciate any suggestion on it. Following is the description of my problem and I am also attaching the *.nb file to explain it further. Thanks a lot for your help
I have two functions S and X such that:
S is a summation of 30 f[ i, j] functions and
X is a function of same 30 f[i, j] functions along with another parameter Ea.
I want to find the optimum (minimum) point for S wrt 30 f[i, j] parameters, such that X is constrained to be zero for different values of Ea (for example from 1E5 - 2E6 with the step size of 1E5) along with other constraints defining the range of values of f[i,j]. On trying NMinimize, I am having following issues –
NMinimize searches for the global optimum but does not necessarily find it. That may be the reason for the abrupt variation that you are puzzled about.
