Inconsistencies in problem classification strings

We were discussing the classification of the problems in the CUTest suite and found some inconsistencies specifically regarding how constraints are reported in the classification of nonlinear equation (NE) problems.

As an example, the JUDGENE problem is classified as NOR2-MN-2-20, i.e., having 20 constraints. This is reflected in the dimension obtained when instantiating the problem. Of course, these correspond to the residuals to be minimized.

Conversely, the HATFLDBNE problem is classified as NOR2-AN-4-0, i.e., having no constraints despite having a residual vector with 4 entries.

There are several other instances exhibiting these discrepancies (I wrote a script to detect these kinds of problems).

The question in this regard is which convention should be adopted (zero or the number of residuals, I would prefer the latter) and stick to that convention consistently.

uninstall CUTEst completely in ubuntu?

Update links to CCPForge in wiki

where can I download LP test files?

Where can I download the LP test files? The existing links at https://www.numerical.rl.ac.uk/cute/netlib.html are now dead.

chjprod gives incorrect result when goth = .false.

When calling chjprod on ALLINITC with the default starting point x and Lagrange multipliers y:

double y0 = 3.5;
double p[] = {0.3, 0.3, 0.3, 0.3};
CUTEST_chjprod(&status, &CUTEst_nvar, &CUTEst_ncon, true, x, &y0, y, p, r);
CUTEST_cdh(&status, &CUTEst_nvar, &CUTEst_ncon, x+1.5, y-0.2, CUTEst_nvar, r);
CUTEST_chjprod(&status, &CUTEst_nvar, &CUTEst_ncon, true, NULL, &y0, NULL, p, r);
CUTEST_chjprod(&status, &CUTEst_nvar, &CUTEst_ncon, true, x+1.5, &y0, y-0.2, p, r);

gives

chjprod: [  4.2   2.1   8.4 -10.5]
chjprod: [ 94.314672   100.74225564 128.62426465  78.6433218 ]
chjprod: [330.40135202 352.89789475 450.18492627 275.25162631]

which is clearly incorrect.

Undefined symbols

@nimgould
I have the following missing symbols when I generate the shared library libcutest.${dlext}.
Do I need to include some additional .o files?
I can't compile it on MacOS and Windows.

In SifDecode, you provide additional .o files when you decode a problem (RANGE.o, ELFUN.o, GROUP.o, EXTER.o).
Can we add them by default in the library or they are related to each SIF problem?

problem files do not have f90 extension

Line 434 of runcutest tries to compile the problem files with an f90 extension. Is that intentional? That causes an error for me on macOS. I wonder how anyone has been able to use runcutest?! Those files have extension f. This fixes it for me:

434c434
<         command="${FORTRAN} ${PROBFLAGS} ${i}.f90"

CI tests failing on macos

Both macos CI tests are failing. The one for gnu seems not to find gfortran,
while the one for intel goes through an infinite loop when deciding which compiler
to use.

Parallel compilation

I noticed after some debugging that the standard command

$ARCHDEFS/install_optrove

uses make internally to compile libcutest.a. Unfortunately, the compilation rule uses commands modifying the file libcutest.a in place. The compilation therefore breaks whenever multiple threads are used (i.e., using make -j<n> or by having MAKEFLAGS="-j<n>" set in the environment).

Since the behavior is unpredictable and errors of the form

/usr/bin/ar: /cutest/cutest/objects/pc64.lnx.gfo/double/libcutest.a: error reading cutest.o: file truncated 
/usr/bin/ar: /cutest/cutest/objects/pc64.lnx.gfo/double/libcutest.a: malformed archive

are not caught, the compilation can silently fail. I think it would be a good idea to put a warning in the wiki to.

Segmentation Fault when solving problems with most recent version of Ipopt

Issue Overview: I followed the directions in $CUTEST/src/ipopt/README.ipopt for getting Ipopt running with CUTEst but Ipopt with CUTEst results in a segmentation fault.

I recently installed Ipopt version 3.13.3 and have been unable to solve problems with Ipopt using CUTEst. In particular, I am experiencing a segmentation fault from an invalid memory reference. I did a quick edit of runcutest to run with Valgrind and have included the output below. The following three outputs are included below:

(1) Indication that Ipopt was able to pass the tests upon installation
(2) Console output on attempt to solve BIGGSC4 with Ipopt
(3) Console output on attempt to solve BIGGSC4 with Ipopt with Valgrind in runcutest

(1) Console output indicating Ipopt 3.13.3 has been successfully installed on machine:

and many more (3,064) such leaks in cutest_usetup and cutest_udimsh (all that I tested).

While this may not seem significant it very quickly adds up when one loops over several different problems!

From the traceback it is clear that these leaks are coming from the Fortran (namely the functions cutest_allocate_array_integer, cutest_usetup_threadsafe, and cutest_initialize_workspace in this snippet) possibly automatic array deallocation is failing for some reason? It is probably worth running both the Fortran and C interfaces to cutest_usetup and cutest_udimsh through valgrind or -fsanitize=address to test for these memory leaks.

Installation Problems

My computer is an intel MacBook, but there was a problem during the final installation and Matlab connection. I would like to ask for help.

Issue in installing gfortran-4.3

Dear Prof. Gould,

I was tying to install CUTEst and its interface with MATLAB via the instruction from https://github.com/ralna/CUTEst/wiki. I'm using 64-bit max osx system. I have gone to the step of

"Now move to the ./cutest directory, enter the command $ARCHDEFS/install_optrove and follow the instructions."

When I change the directory and enter $ARCHDEFS/install_optrove, the first question is "Do you wish to install CUTEst (Y/n)? " I enter ``Y".

The second question is "Do you require the CUTEst-Matlab interface (y/N)?" I enter Y., Then I select platform "13", which is "64-bit MAC OS/X".

Then the third question is "Would you like to review and modify the system commands (y/N)?" I enter "N". Then I select Matlab version "4", which is "R2016b-R2017b", since I'm using R2017a.

Then, it results in a warning "Warning: you need to install gfortran-4.3 to allow
for Matlab and CUTEst interaction. Aborting".

How to fix this issue? I think I have installed gfortran 10.2 from https://github.com/fxcoudert/gfortran-for-macOS/releases, though it's not 4.3. I also tried to run brew install gcc on the terminal, but the warning is still on.

Is there a way to fix this issue?

Although this is warning, I think I haven't installed CUTEst successfully. When I run the test by
cutest2matlab_osx LUBRIFC.SIF

I got the result like

Function values and derivatives inconsistent?

Jean-Pierre Dussault reported the following behaviour using the Julia interface to CUTEst, but I can reproduce it directly in Fortran. The idea is to compare the values and derivatives of t -> f(x - tg) where x is the initial guess and g the gradient of the objective at the initial guess.

If I stick the following into, e.g., gen90_main.f90:

  OPEN(69, FILE='TVALS.dat', FORM='FORMATTED', STATUS='NEW')
  OPEN(70, FILE='FVALS.dat', FORM='FORMATTED', STATUS='NEW')
  OPEN(71, FILE='GVALS.dat', FORM='FORMATTED', STATUS='NEW')

  tmin = 0.120
  tmax = 0.124
  dt = (tmax - tmin) / 10000

  ALLOCATE(G(n), Gt(n), Xt(n))
  CALL CUTEST_ugr(status, n, X, G)

  DO i = 0, 10000
    t = tmin + i * dt
    WRITE(69, '(D22.15)') t
    Xt = X - t * G
    CALL CUTEST_ufn(status, n, Xt, Ft)
    WRITE(70, '(D22.15)') Ft
    CALL CUTEST_ugr(status, n, Xt, Gt)
    slope = -DDOT(n, Gt, 1, G, 1)
    WRITE(71, '(D22.15)') slope
  END DO

  DEALLOCATE(Xt, Gt, G)
  CLOSE(71)
  CLOSE(70)
  CLOSE(69)

and run runcutest -p gen90 -lblas -D VAREIGVL, and plot the values in FVALS.dat and GVALS.dat, I obtain

Thus the slope is zero around t = 0.123. However, f appears to attain its minimum before 0.121, where the slope is not small.

Would this be related to an error in the SIF file, the decoder, the gradient computation, or between the screen and the chair?

Issue in installing CUTEst and its MATLAB interface

Dear Prof. Gould,

I was trying to install CUTEst in order to test some unconstrained minimization algorithms in MATLAB on the cutest problems.
I am working on a linux (lubuntu 18.10) 64-bit virtual machine with Matlab R2018b and the gcc-6, gfortran-6, g++-6 compilers set as default.
I have issues in installing cutest and its interface with MATLAB.

By following the instructions i move to $CUTEST and enter "$ARCHDEFS/install_optrove". The script wants to run "./bin/install_optrove", but since the current directory is "./cutest" it cannot find the file.
I then decided to run directly "$ARCHDEFS/bin/install_optrove" and apparently both sifdecode and cutest were compiled in the right way. Since I was using gcc-6.5 and not gcc-6.3 I got the following message

Compiling mcutest Building with 'gcc'.
Warning: You are using gcc version '6.5.0'. The version of gcc is not supported. The version currently supported with MEX is '6.3.x'. For a list of currently supported compilers see: https://www.mathworks.com/support/compilers/current_release.
MEX completed successfully.
[ OK ]
CUTEst: matlab (double precision version) compiled successfully

I guess that, despite the different compiler version, everything went in the right way.
(gcc-6.3 is not available through standard repositories... in order to get it I should compile it from the source. I tried, but my attempt to do so was not successfull.)

What happens is that if I try to run "cutest2matlab" in order to decode a problem and use it on MATLAB, I get the following output:

pc64.lnx.gfo
[...]
File successfully decoded

ERROR: Cannot find a matlab definitions file in
/home/mviola/Documents/CutestExecutables/cutest/packages/pc64.lnx.gfo/double
or
/home/mviola/Documents/CutestExecutables/cutest/packages/defaults

Is there a way I can fix this issue?

Best regards,
Marco
