Welcome to the web page of the SIMCO Lorentz Center workshop. SIMCO stands for Set- and Indicator-Based Multi-Criteria Optimization. The SIMCO workshop took place September 2-6, 2013 at the Lorentz Center in Leiden, The Netherlands. During this workshop, we studied geometrical and algorithmic foundations of set-oriented and indicator-based multi-criteria optimization.

The workshop featured four major topics, all related to SIMCO:

1. On appropriate set preferences and indicators
2. The design of set-oriented variation operators
3. Links to (computational) geometry
4. Towards SIMCO for non-standard problems

All presentations will be collected here.

Please add your working group results here.

1. Characterization of local optimality w.r.t. unary / n-ary set indicators
2. Preference articulation on sets of solutions (several different non-standard problems (NSP) included, see below)
3. Performance assessment: Statistics on sets, multiple runs
4. Subset selection algorithms: approximation algorithms + exact. (limits?)
5. Indicators for NSP, computational efficiency, optimal sets
6. Population/set- vs. individual/element - level approach
7. Interaction with the user: tools (visualisation in higher dimensions), interaction schemes / workflows, interactive decision map, Multi Criteria Decsision Aid (MCDA), groups of decision
8. Parameter adaptation, operator selection, bandits, learning, self-adaptation
9. Run-time analysis, performance guarantees
10. (Computational) geometry aspects of MOO (solution sets)
