This archive contains the test problems used in the paper:

Ploskas, N. and N. V. Sahinidis, Review and comparison of algorithms
and software for mixed-integer derivative-free optimization,
Journal of Global Optimization, 82, 433-462, 2022.

See the paper itself for original sources of these problems.

The folder named bam provides input files for the BAM solver from minlp.com.
These can be placed in any folder of your choice. The folder named ps22
contains OSX Intel executables for the test problems.
The BAM files assume that ps22 will be located in
/usr/local/testlibs/dfo/ps22. If a different location
is desired, modify the dataprovider line in the BAM files.

Two of the 267 executables are currently not available for this platform
due to compiler limitations. If you are interested in them, try to compile them
from the source files or contact us at info@minlp.com in case we are able to
provide them.
