| Research Abstract |
In this study, we proposed algorithms for some graph optimization problems. It is known that the problem to recover drawing order from static handwritten line images is modeled by a graph optimization problem. We designed a heuristic algorithm for this problem by using spline curve. Also, we recursively define a class of graphs those represent some line images. Then, we proposed a linear-time algorithm for the class. We also investigated differential approximation for k-VRP(1,2) and MaxTSP.
