Tree decomposition compression using tree grammar and query processing based on answer set programming
Kazuyuki Kojima, Hiroyuki Seki (Nagoya Univ.) DE2021-16
Abstract (in Japanese) (See Japanese page) 
(in English) Tree decomposition of a graph is an effective approach to solving problems for large graphs while the decomposition itself needs much time in general.In the previous work, we proposed a method of compressing a decomposed tree and directly manipulating the compressed data.However, a query must be manually written assuming a compressed data.
In this paper, we propose a query processing method based on answer set programming.A user can write a query in a declarative way without assuming a compressed data and the query can be translated into a program that directly manipulates a compressed data.The paper shows the experimental results conducted in our prototype system implemented by Clingo and C++.
