Hans Mittelmann
Selected benchmarks in continuous and discrete optimization

 

Abstract:
From our benchmarks at, http://plato.asu.edu/bench.html we will quote the discrete and some of the continuous benchmarks. The discrete benchmarks are partly based on MIPLIB 2010. The continuous benchmarks include LP/QP, QCQP, SOCP, and SDP.

Extending the conic optimizer in MOSEK with semidefinite cones

 

Abstract:
We discuss the conic optimizer in MOSEK with a special emphasis on the recent semidefinite capabilities in the solver.

Presolve for linear and mixed-integer programming

Coauthors: Zonghao Gu, Ed Rothberg

 

Abstract:
For linear programming, presolve typically amounts to reducing the size of the model; however, for mixed-integer programming the changes can be much more fundamental, producing a model "strengthening'', where this strengthening doesn’t simply speed the solution process, but can be the difference between a model being solvable and hopeless. We will examine the effect of presolve, including the effects of some of the key reductions as well as some of the more interesting new reductions that have been discovered over the last several years.
