hi dear all; please consider a geometric programming problem such as attached example. this is the cost function of a GP problem. can this function be a convex function without any variable change?
Michael Patriksson
What do you mean by "without any variable change"? A variable transformation?
Well, as Richard states - your rather simple function is strictly convex on the positive axis.
How does this thing relate to geometric programming?

the main function was in the attached form .a gp problem with two variables. i normalizd x1 to 1 for convenience . is this convex now? i doubted it because we used a logarithmic change for transform to the standard convex form. thanks
