Abstract (in Japanese) (See Japanese page) 
(in English) The term ``Conference'' means an academic meeting in general for
presentation and discussion on scientific research/education activities,possibly including refereeing procedures. There are many intermediate processing steps before the completion. Among them session scheduling takes much effort and long processing time, because several dozen to thousand papers may have to be handled. It is a combinatorial optimization problem for maximize or minimize a given objective function
under some constraints, such as avoiding assignments of chairpersons to the time slots for presentation of their papers. The problem is known to be NP-hard. Requirements are divided into hard ones and soft ones. All hard ones have to be satisfied, while it is desirable that as many soft ones as possible are met. Hence the objective is to obtain a conference timetable satisfying all hard requirements and as many soft ones as possible. In this research, we focus on the local search method (LS for short), well-known as heuristics for combinatorial optimization, propose a new algorithm based on the method, and evaluate its capability by means of results of computing experiment. Also explained are several functions implemented for supporting session scheduling. This paper reports current status of developing the proposed system.
