Title
On the hardness of turn-angle-restricted rectilinear cycle cover problems
Abstract
A cycle cover of a graph G is a collection of disjoint cycles that spans G. Generally, a (possibly discon- nected) cycle cover is easier to construct than a con- nected (Hamiltonian) cycle cover. One might expect this since the cycle cover property is local whereas connectivity is a global constraint. We compare the hardness of CONNECTED CYCLE COVER and CY- CLE COVER under various constraints (both local and global) on the orientation, crossings, and turning an- gles of edges. Surprisingly perhaps, under specific con- straints, the cycle cover problem is NP-hard whereas the corresponding connected cycle cover problem can be solved in polynomial time.
