Preface
This volume consists of the peer-reviewed papers of the China-Japan Conference on Discrete Geometry, Combinatorics and Graph Theory (CJCDGCGT 2005). The conference was held in two places in China—Nankai University, Tianjin (November 18-20, 2005) and Northwestern Polytechnical University, Xi’an, Shaanxi (November 22-24, 2005). The conference sponsors include the Center for Combinatorics of Nankai University, the Department of Applied Mathematics of Northwestern Polytechnical University and the Institute for Education Development of Tokai University of Japan. More than 200 participants from China, Japan, USA, Malaysia, Mexico, Thailand, Iran, etc. attended. The opening ceremony was chaired by the Vice-President of Nank
