The BiqBin team met in Ljubljana at the 3rd Klagenfurt-Ljubljana OR Workshop. The recent developments were presented and the organization for the next months was done.

In the workshop, the main topics covered:
- new implementation of the website,
- improvements of the exact penalty method,
- bounding and parallelization,
- status of the code.

Then, the plans for the next months were made.
Overall the members are very satisfied about the project and look forward to publish the results in high-quality journals and conferences.

BiqBin at IPCO

24. 5. 2019, Elisabeth Gaar

Nicolo Gusmeroli and Elisabeth Gaar presented their work at IPCO.

Two researchers of the BiqBin project presented their work at IPCO (Integer Programming and Combinatorial Optimization) 2019 in Ann Arbor, Michigan, USA.

Nicolo Gusmeroli presented in the poster session. The poster rose a lot of interest and Nicolo answered a lot of questions.

The paper "A Bundle Approach for SDPs with Exact Subgraph Constraints" by Elisabeth Gaar and Franz Rendl was accepted at the highly competitive conference IPCO and therefore Elisabeth Gaar gave a talk. As a next step the results of the paper will be included into BiqBin.

Nicolo Gusmeroli visited Prof. Sam Burer (University of Iowa)

Nicolo Gusmeroli stayed three weeks in Iowa City for research. He was a visitor of Prof. Sam Burer and together they worked on the relaxations for the exact penalty method over discrete sets.
