Re: [R] CRAN package NlcOptim query

[Hans W Borchers]

The maintainer of the *NlcOptim* package told me that he has fixed the
problem and already submitted a new version to CRAN. Thanks, XianYan,
for this prompt reaction.

Re: [R] CRAN package NlcOptim query

[Hans W Borchers]

To be corrected:
`Constr_new` with a capital letter;
`aeq2` is a list, should be a matrix.

As I said last month, you can yourself combine inequality constraints
with bounds constraints as follows:

myA <- rbind(-Constr_new, diag(-1,numel), diag(1,numel))
myB <- c(-x_than0, rep(0,numel), rep(1,numel))

and `solnl` will return a result like this:

sol <- NlcOptim::solnl(X = c(InputTM), objfun = obj_F, A = myA, B = myB,
   Aeq = as.matrix(aeq2), Beq = beq2)
c(sol$par)
[1] 0.8310997170, 0.0378150241, ..., 0.2463006547, 1.00
sol$fn
[1] 0.00421616

I will write to the maintainer asking about why this example does not
work --  supplying functioning code, maybe that will trigger a
response.

Please note: You are sending e-mail in HTML format which makes it
almost impossible to use as code in the R console.

[aveek via R-help]

Hi Eric,
Yes, in fact I did mention in my 1st email that I am posting this here as the 
package maintainer did not respond even after a couple of emails.
Thanks,Aveek

Hello Eric,

Thanks for your response and suggestions. 

I have used dput() on the R objects - sharing below so that it is possible for 
anyone to recreate the situation.

I have still kept it as a 9*9 matrix but for simplicity we now only have 2 
equality and 2 non equality constraints.

Thanks again for your help.

[Eric Berger]

Aveek,
Did you try contacting the package maintainer as Hans suggested?

Re: [R] CRAN package NlcOptim query

[Hans W Borchers]

This is still not complete: `x_than0` is missing.
`Constr_new` is written with a capital 'C'.
And aeq2 is a list of column vectors, not a matrix.
Setting the tolerance to 0 does not seem to be a good idea.

Making aeq2 a matrix and adding `x_than0 <- matrix(c(1, 1))`, then

aeq2 <- as.matrix(aeq2)
x_than0 <- matrix(c(1, 1))

NlcOptim::solnl(X=c(InputTM), objfun=obj_F, A=-Constr_new, B=-x_than0,
Aeq=as.matrix(aeq2), Beq=beq2,
lb=c(rep(0,numel)),ub=c(rep(1,numel)), tolX = 0)

will indeed return in the same error, while it runs without error if you
either leave out the inequality constraints or the bounds constraints. So
I guess there may be a bug when the function internally combines these
constraints and the bounds.

You could / should write to the maintainer. I know he is very responsive.

For the moment, you can combine the bounds constraints and the lower and
upper bounds yourself:

myA <- rbind(-Constr_new, diag(-1,numel), diag(1,numel))
myB <- c(-x_than0, rep(0,numel), rep(1,numel))

NlcOptim::solnl(X=c(InputTM), objfun=obj_F, A=myA, B=myB,
Aeq=as.matrix(aeq2), Beq=beq2)

returns "constraints are inconsistent, no solution!", but that may be the
case because I don't know your `x_than` value.

Re: [R] CRAN package NlcOptim query

Hello Eric,

Thanks for your response and suggestions. 

I have used dput() on the R objects - sharing below so that it is possible for 
anyone to recreate the situation.

I have still kept it as a 9*9 matrix but for simplicity we now only have 2 
equality and 2 non equality constraints.

Thanks again for your help.

Re: [R] CRAN package NlcOptim query

Hi Aveek,
1. This is an "all-text" mailing list. Your attachment did not come
through.
You can check out the posting guide (see the link at the bottom of your
email)
 and/or
 use dput(...) on your structures and paste them into your email so
that members of the list can try to reproduce the problem.
2. One way to check out whether you are using a package correctly is to try
a tiny example that you can calculate by hand, and see if you can reproduce
the solution via the package.
e.g. instead of a 9x9 matrix (hence 81 dimensional problem in your
case), try a 2x2 matrix with maybe just one or two constraints.

HTH,
Eric

[R] CRAN package NlcOptim query

[aveek via R-help]

Hi All,
I am facing an issue with an optimization problem which I am trying to solve 
using NlcOptim package in R. I have tried reaching out to the package 
maintainer but not received any response, hence posting this here. 

 
Below is the code snippet I am using:
 
  
 
#Optimization
 
  obj_F <- function(vect_mat){
 
    return (sum((c(InputTM) - vect_mat)^2))
 
  }
 
  
 
  numel = nrow(InputTM)*ncol(InputTM)
 
  opt_vect = solnl(X=c(InputTM), objfun=obj_F, A=-constr_new, B=-x_than0, 
Aeq=as.matrix(aeq2), Beq=beq2, lb=c(rep(0,numel)),ub=c(rep(1,numel)),tolX = 0)
 
  
 
I am attaching in the email the data being used as function arguments.
 
  
 
Input_TM is a 9*9 matrix
 
Constr_new is a 120*81 matrix
 
x_than0 is a 120*1 matrix
 
aeq2 is a 17*81 matrix
 
beq2 is a 17*1 matrix
 
  
 
Below is the error I am getting :
 
  
 
R>   opt_vect = solnl(X=c(InputTM), objfun=obj_F, A=-constr_new, B=-x_than0, 
Aeq=as.matrix(aeq2), Beq=beq2, lb=c(rep(0,numel)),ub=c(rep(1,numel)),tolX = 0)
 
Error in as.matrix(A %*% Xtarget) - matrix(B, ncol = 1) :
 
  non-conformable arrays
 
Calls: solnl -> rbind -> rbind
 
In addition: Warning message:
 
In rbind(rbind(lbright, ubright), B) :
 
  number of columns of result is not a multiple of vector length (arg 2)
 
Calls: solnl -> rbind
 
  
 
Enter a frame number, or 0 to exit  
 
  
 
1: solnl(X = c(InputTM), objfun = obj_F, A = -constr_new, B = -x_than0, Aeq = 
as.matrix(aeq2), Beq = beq2, lb =
 
2: rbind(rbind(rbind(Aeq %*% Xtarget - Beq, as.matrix(nceq)), as.matrix(A %*% 
Xtarget) - matrix(B, ncol = 1)), a
 
3: rbind(rbind(Aeq %*% Xtarget - Beq, as.matrix(nceq)), as.matrix(A %*% 
Xtarget) - matrix(B, ncol = 1))
 
  
 
  
 
  
 
Can you kindly help with this? I am mostly sure that the constraint matrices 
have been correctly formulated. Am I going wrong with the way I am specifying 
the arguments?
 
Thanks a lot for any help any of you can offer.
 
  
 
Thanks and Regards,
 
Aveek Mukhopadhyay
