Help in Optimization of a function
2 messages · Raghuraman Ramachandran, Rui Barradas
Hello, You don't need an optimzation routine to know that the maximum of this function is +Inf. It's attained at z = 0+ (when z converges to zero by positive values). This breaks the R function optim(), by the way. It " needs finite values of 'fn' " Hope this helps, Rui Barradas Em 08-07-2012 10:15, Raghuraman Ramachandran escreveu:
guRus! I have a function f = exp(x^2-y+(1/z)) Also, x can take values from 1 to 37, y from 2 to 20 and Z from -13 to 51. How can I find the maximum of f using any of the optimization functions please? Is there a way to store the possible values of x, y and Z in a single variable like in a List or in a multi-dimensional array? Thanks for your help Raghu [[alternative HTML version deleted]]
