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:

form matrix nlp

problem := ur+dr, {con1, con4, con5}, seq(w[i] = 0 .. 1, i = 1 .. N):
problem_matrix_form := Optimization:-Convert:-AlgebraicForm:-LPToMatrix(problem):

Optimization:-LPSolve(problem, maximize = true);
Optimization:-LPSolve(problem_matrix_form[2 .. 4], maximize = true);


The above trick-conversion method works for all LP and QP problems
However it does not work on NLP problems. I have attached the workshet
