电竞投注        an orientation of g is a digraph obtained from g by replacing each edge by exactly one of two possible arcs with the same endpoints. we call an orientation proper if neighboring vertices have different indegrees. the proper orientation number of a graph g, is the minimum maximum indegree of a proper orientation of g. in this talk, we will introduce some progress on proper orientation of graphs.joint work with jiangdong ai, stefanie gerke, ruijuan gu, gregory gutin, hui lei, and zhenyu taoqiu.
