DESCRIPTION:

NOMAD is a C++ implementation of the Mesh Adaptive Direct Search (MADS)
algorithm, designed for constrained optimization of black-box functions.

The algorithms implemented are based on the book
"Derivative-Free and Blackbox Optimization", by Charles Audet and Warren Hare,
Springer 2017.

VERSION WARNING:

This repository is for NOMAD 4. The previous version, NOMAD 3,
is not on GitHub. NOMAD 3 will be deprecated in the future.

NOMAD 4 is similar in usage to NOMAD 3.

NOMAD 4 has a new software architecture, uses OpenMP to run
evaluations in parallel, and also has some new functionalities.

HOW TO CITE:

Please cite NOMAD 4 with reference:

COMPILATION (Release):

On Linux, Unix, Windows and Mac OS X, NOMAD can be compiled using CMake.
The minimum version of CMake is 3.14. Older versions will trigger
an error. A recent C++ compiler is also required.

Before starting the procedure, we recommend setting the environment variable
$NOMAD_HOME with the path where NOMAD has been copied. For Linux and OSX,

export NOMAD_HOME=/home/myUserName/PathToNomad

For Windows, add an environment variable %NOMAD_HOME% containing the path.
The remaining text uses the $NOMAD_HOME environment variable.

The procedure is the following. On the command line in the
$NOMAD_HOME directory:

cmake -S . -B build/release
---> Create the CMake files and directories for building (-B) in build/release.
The source (-S) CMakeLists.txt file is in the $NOMAD_HOME directory.

To deactivate compilation with OpenMP:
cmake -DTEST_OPENMP=OFF -S . -B build/release

To enable *C interface* building:
cmake -DBUILD_INTERFACE_C=ON -S . -B build/release

To enable *Matlab* interface building:
cmake -DBUILD_INTERFACE_MATLAB=ON -DTEST_OPENMP=OFF -S . -B build/release

! Before proceeding, have a look into
$NOMAD_HOME/interfaces/Matlab_MEX/readme.txt

! Extra flags might be required to prevent CMake errors.

! Compiler version and Matlab version need to be compatible;
! Check https://www.mathworks.com/support/requirements/supported-compilers.html

! The Matlab interface will not be built if OpenMP is enabled.

! An extra addpath Matlab command must be done to have access
to nomad Mex binaries:
addpath(strcat(getenv('NOMAD_HOME'),'/build/release/bin'))

To enable *Python* interface (PyNomad) building:
cmake -DBUILD_INTERFACE_PYTHON=ON -S . -B build/release

! Before proceeding, have a look into
$NOMAD_HOME/interfaces/PyNomad/readme.txt

! More details are provided in $NOMAD_HOME/interfaces/PyNomad/readme.txt

! Building requires Cython. Cython can be obtained with
Anaconda distribution platform.

! On *Windows*, using Visual Studio, see the user guide or the README
to properly manage x86/x64 building of binaries.

To enable *Java* interface building (with Swig):
cmake -DBUILD_INTERFACE_JAVA=ON -S . -B build/release

cmake --build build/release --config Release (for *Windows*)
or
cmake --build build/release (for *OSX* and *Linux*)
---> Build all the libraries and applications

Option --parallel xx can be added for faster build.

The option --config Release should be used on *Windows*
multi-configuration build environment (VisualStudio) to build only
Release configuration. The default configuration is Debug.
The same option should be used for *OSX* when using a *Xcode* project.

cmake --install build/release --config Release (for *Windows*)
or
cmake --install build/release (for *OSX* and *Linux*)
---> Copy binaries and headers in build/release/[bin, include, lib]
and in the examples/tests directories.

By default, the executable "nomad" will be installed into the directory:
build/release/bin/ (build/debug/bin/ when in debug mode). A symbolic link
is added in the bin directory (not functional for windows).

It is possible to build only a single application in its working directory:
(with NOMAD_HOME environment variable properly set)

cd $NOMAD_HOME/examples/basic/library/example1
cmake --build $NOMAD_HOME/build/release --target example1_lib.exe
cmake --install $NOMAD_HOME/build/release


COMPILATION (Debug):

The procedure to build the debug version is the following.
On the command line in the $NOMAD_HOME directory:

cmake -S . -B build/debug -D CMAKE_BUILD_TYPE=Debug
---> On *Windows*, all 4 configurations are configured
(Debug, RelWithDebugInfo, MinSizeRel, Release); flag
CMAKE_BUILD_TYPE is ignored.

cmake --build build/debug --config Debug (for *Windows*)
or
cmake --build build/debug (for *OSX* and *Linux*)
---> Build the libraries and applications

Option --parallel xx can be added for faster build.

cmake --install build/debug --config Debug (for *Windows*)
or
cmake --install build/debug (for *OSX* and *Linux*)
---> Copy binaries and headers in build/debug/[bin, include, lib]
and in the examples/tests directories


EXAMPLES OF OPTIMIZATION:

Batch Mode:
There are examples in batch mode in $NOMAD_HOME/examples/basic/batch/.
In each directory, the blackbox functions (usually named bb) are compiled
by default. The problem may be resolved using NOMAD and the parameter file:

$NOMAD_HOME/build/release/bin/nomad param.txt

For convenience, the path to $NOMAD_HOME/build/release/bin directory
can be added to the $PATH environment variable. For *Windows*, this is
achieved by setting the parameters for environment variable %PATH% to
%NOMAD_HOME\build\release\bin\


Library Mode:
There are examples in library mode in $NOMAD_HOME/examples/basic/library/.
In each directory, the executable may be compiled when building
the NOMAD application. The problems may be resolved by execution,
for instance:

./example_lib.exe

IMPORTANT: Library mode examples with *Windows* require to set
the %PATH% environment variable (see above). Otherwise, the executables
cannot find NOMAD dlls.
