18th Cologne-Twente Workshop on Graphs and Combinatorial Optimization

June 15-17, 2020
Hotel Re Ferdinando
Ischia – Italy


The Cologne-Twente Workshop on Graphs and Combinatorial Optimization 2020 welcomes contributions on theory and applications of discrete algorithms, graphs and combinatorial optimization in the wider sense.

The series of Cologne-Twente Workshops on Graphs and Combinatorial Optimization started with meetings organized every two years by the universities of Cologne and Twente. The organizational base was later expanded by other universities. Since 2003 the workshop is held (almost) every year.

CTWs are especially intended to let doctoral students and young researchers present the results of their research activities in a friendly and highly interactive atmosphere.

As is customary for CTW, the workshop will be held over three days (June 15-17, 2020).
