I'm trying solve a problem with NLPSolve using procedures like constraints, but it say: Error, (in Optimization: -NLPSolve) constraints must be specified as a set or list of procedures. Theses constraints are inequality and equality.  How i can get procedures as a list or set?. Is there anyone to give a example of it?. Thanks!

Dear all!.       

I have an expression with ramdom variables. Can i use NLP to optimize it?. In this case, does Maple take the histogram of theses ramdom variables?. Thank!!!

I have excuted a loop for i from.....by...while.....do l2:=NLPSolve(.......) with variables, t1,th,tl, etc. I need get the numerical result of theses variables and assign them to t1,th, etc. After execute a function with them. I have tried with op, map and assign, but the program don't understand the numerical value of variables. Why?. How can i assign theses numerical vaules?. Thanks! 

Two weeks ago i didn`t have problem with calculate and plot this pareto`s frontier. I got plot it, but if i try it now, i can´t . Why?.

Before

f1 := (1+x1^2+4/3*(x2^2+1))/(x1+x2); f2 := (1+x1^2+3/4*(x2^2+1))/(x1+x2);

with(plots); with(Optimization); ind := 1; ans := Array(); for i from 1.73205080756887853 by 0.1e-4 while i < 2.87500000000000000 do roll := i; f1max := NLPSolve(f1, {f2 = i}, x1 = 0 .. 2, x2 = 0 .. 3, method = sqp, maximize = false); ans := proc (ind) options operator, arrow; [op([1], f1max), roll] end proc; ind := ind+1 end do; ans;

st := time[real]();

               Array(%id = 18446746983952876598)

pointplot(convert(ans, list));

 After

with(plots); with(Optimization); ind := 1; ans := Array(); for i from 1.73205080756887853 by 0.1e-4 while i < 2.87500000000000000 do roll := i; f1max := NLPSolve(f1, {f2 = i}, x1 = 0 .. 2, x2 = 0 .. 3, method = sqp, maximize = false); ans := proc (ind) options operator, arrow; [op([1], f1max), roll] end proc; ind := ind+1 end do; ans;

st := time[real]();

                              ans
pointplot(convert(ans, list));
Error, (in plots:-pointplot) number of elements in list must be a multiple of 2  (????)

hello!, How can i to plot the next data in a 2D plot?. it is the result of a loop for.... do....while. I had tried with pointplot anda dataplot, but must be something wrong!

with(plots);
for i from 1.73205080756887853 by 0.5e-2 while i < 2.87500000000000000 do roll := i; f1max := NLPSolve(f1, {f2 = i}, x1 = 0 .. 2, x2 = 0 .. 3, method = sqp, maximize = false); c := op([1], f1max), print(c, roll) end do; plot(roll, c);
