Introduction The test set provides a large collection of nonconvex problems consisting of quadratic, binary quadratic and integer quadratic programs. At a Glance The size of the unzipped dataset is ~803MB. The dataset contains the instances used in the manuscript “Spectral Relaxations and Branching Strategies for Global Optimization of Mixed-Integer Quadratic Programs” by Nohra, Raghunathan and Sahinidis (see Citation section). Files in the unzipped folder: README.md BoxQP_instances_data/ CBQP_instances_data/ EIQP_instances_data/ QSAP_instances_data/ TestSetDescription.pdf. The format of the test instances are described in TestSetDescription.pdf.
