,Edge-Cut Width: An Algorithmically Driven Analogue of?Treewidth Based on?Edge Cuts,-hard parameterized by treewidth, a natural alternative would be to use a suitable analogue of treewidth that is based on edge cuts instead of vertex separators. While tree-cut width has been coined as such an analogue of treewidth for edge cuts, its algorithmic applications have often led to disapp

The corresponding decision problems, ., . and ., are well studied both on general graphs and on special graph classes. We prove a number of new ., .[1]-hard and para-.-complete results by considering a hierarchy of parameters of the

In 2021, Duarte, Oliveira, and Souza [MFCS?2021] showed some problems that are FPT when parameterized by the treewidth of the complement graph (called co-treewidth).

,Extending Partial Representations of?Circular-Arc Graphs,We consider this problem for circular-arc graphs, where several arcs are predrawn and we ask whether this partial representation can be completed. We show that this problem is .-complete for circular-arc graphs, answering a question of Klavík et al.?(2014)..We complement this hardness with tractabil
