On the connectivity of the flip graph of plane spanning paths
Flip graphs of non-crossing configurations in the plane are widely studied objects, eg, flip

Reconfiguration of plane trees in convex geometric graphs
A non-crossing spanning tree of a set of points in the plane is a spanning tree whose edges
pairwise do not cross. Avis and Fukuda in 1996 proved that there always exists a flip …

Short flip sequences to untangle segments in the plane
A (multi) set of segments in the plane may form a TSP tour, a matching, a tree, or any
multigraph. If two segments cross, then we can reduce the total length with the following flip …

How can we reconfigure a given set of n segments with fixed endpoints in the plane into a
crossing-free set? We remove a pair of crossing segments and insert one of the two pairs of …
