    Our aim is to design algorithms for discrete optimization problems with graph structure. We have obtained approximation algorithms and exact algorithms for several NP-hard but important problems such as the maximum independent set problem.
    We have theoretically analyzed the approximation ratios of our approximation algorithms and derived upper bounds on the time complexities of our exact algorithms.
    In particular, for designing exact algorithms, we have devised new design techniques such as amortization by shifts, decomposition by cut-pairs,and how to compute the largest root of a set of recursive equations.

    Network design problem is a combinatorial optimization problem the goal of which is to construct efficient and stable networks or to control networks effectively. In this research, we considered general models that capture a variety of tasks which are important in applications, and investigated them to develop algorithms. In particular, we have obtained new results for problems such as survivable network design problems with connectivity and degree constraints, submodular partition problem, graph orientation problem with set-connectivity demands, and source location problem.

    In this study, we proposed "Multi-sphere Scheme" to efficiently pack given two- or three-dimensional objects in a compact space, designed all the components of the scheme, and investigated fundamental theory on geometrical packings and graph drawings. We designed an algorithm that can directly transform given triangle-mesh data into data for Multi-sphere Scheme based on a graph-theoretical analysis. We developed a 3D visual interface for Multi-sphere Scheme, by which we can easily check computational results in a visualized form. We greatly improved our solver for packing rectangles so that a long-standing open benchmark instance is solved for the first time by our new solver. As for the theory part, we found a 2D representation of triconnected graphs so that a useful triconnected decomposition can be easily obtained, and a characterization of the graphs of non-convex polytopes in a certain class.In particular, the latter result is the first such result since Steinitz' theorem, a characterization of the graphs of convex polytopes is found 80 years ago.
