Hi all,

I try to solve the following nonlinear programming problem:

NLPSolve((int((c[0]+c[1]*u+c[2]*u^2)^2, u = -a .. a))^(4/5)*(int(u^2*(c[0]+c[1]*u+c[2]*u^2), u = -a .. a))^(2/5), variables = [c[0], c[1], c[2]], [int(c[0]+c[1]*u+c[2]*u^2, u = -a .. a) = 1, int(c[0]*u+c[1]*u^2+c[2]*u^3, u = -a .. a) = 0])

but this error message appear:
