Hello!
I'm trying to solve a floor plan problem using a geometric program
with an objective function considering wh, not w + h as in the convex
optimization book. Therefore, I need negative coefficients in g_i what
is not possible, since Real valued logarithm is not defined for
negative values. Is there any workaround to set a constraint like (x -
C)*(x - C) <= t with x and t being variables and C a constant?
cheers
