Finding Forcing on ZDD by Dynamic Programming
Takashi Harada, Shogo Takeuchi (Kochi Univ. of Tech.) COMP2022-33
Abstract (in Japanese) (See Japanese page) 
(in English) Exact cover problem takes a set S and a subset F of the power set of S as an input and determines whether there exists a subset of F that is a partition of S. Combinatorial problems such as graph coloring and vehicle routing as well as puzzles such as sudoku and polyomino can be formulated as an exact cover problem. Since the size of a practical instance can be large, an algorithm that takes an input as zero-suppressed binary decision diagram (ZDD) was proposed. An instance can be transformed into a simpler one based on a binary relation on S called Forcing. In this paper, we propose an algorithm for finding Forcing on ZDD by dynamic programming.
