Here is some of the data used in my papers.
MPS files for the linear and quadratic minimum-distance controlled perturbation instances
(a.k.a. controlled tabular adjustment instances).
Random instance generators
for cell suppression in two-dimensional and two-dimensional hierarchical tables.
for controlled tabular adjustment in three dimensional tables.
Huge CTA instances

Huge 3D L2 CTA instances in MPS format
. They provide huge convex separable quadratic problems.
Some multicommodity network flows instances
I contributed to some of the multicommodity instances maintained in
by Antonio Frangioni.
Seven instances from an integrated refinery problem
