power functions

GAMS
1

Hi,

Are the following functions equivalent (from a computational point of view) in a NLP problem in GAMS ?

f(x)= Power(x,2)
g(x)= x*x
h(x)= x**2

where x is positive.

Thanks,

Omar J. Guerra

For diff between 1 and 3, read http://support.gams.com/doku.php?id=gams:difference_between_the_-operator_and_the_power_function

Between 1 and 2 I don’t really know (my guess is its the same).

Regards
Claudio
