Characterizing Universal Reconfigurability of Modular Pivoting Robots
Hugo A. Akitaya, Erik D. Demaine, Andrei Gonczi +7
We give both efficient algorithms and hardness results for reconfiguring between two connected configurations of modules in the hexagonal grid. The reconfiguration moves that we co…
Negative Instance for the Edge Patrolling Beacon Problem
Zachary Abel, Hugo A. Akitaya, Erik D. Demaine +5
Can an infinite-strength magnetic beacon always ``catch'' an iron ball, when the beacon is a point required to be remain nonstrictly outside a polygon, and the ball is a point alwa…
Path Puzzles: Discrete Tomography with a Path Constraint is Hard
Jeffrey Bosboom, Erik D. Demaine, Martin L. Demaine +3
We prove that path puzzles with complete row and column information--or equivalently, 2D orthogonal discrete tomography with Hamiltonicity constraint--are strongly NP-complete, ASP…
Upward Partitioned Book Embeddings
Hugo A. Akitaya, Erik D. Demaine, Adam Hesterberg +1
We analyze a directed variation of the book embedding problem when the page partition is prespecified and the nodes on the spine must be in topological order (upward book embedding…
