On the Computational Complexity of Generalized Common Shape Puzzles
Mutsunori Banbara, Shin-ichi Minato, Hirotaka Ono +1
In this study, we investigate the computational complexity of some variants of generalized puzzles. We are provided with two sets S_1 and S_2 of polyominoes. The first puzzle asks…

Interval-Memoized Backtracking on ZDDs for Fast Enumeration of All Lower Cost Solutions
Shin-ichi Minato, Mutsunori Banbara, Takashi Horiyama +3
In this paper, we propose a fast method for exactly enumerating a very large number of all lower cost solutions for various combinatorial problems. Our method is based on backtrack…
