Research Projects

  • Novel optimization methods for optimal selection problems from tree breeding

    For tree breeding, one of important goals is to determine the optimal contributions of genotypes that maximize the total benefit under a constraint for genetic diversity. In this project, we exploit a structure of the genetic-diversity constraint which can be described with second-order cone, and propose efficient optimization methods.

  • Optimization approaches for operation-room assignment

    The assignment of surgery operations to operation rooms is an important factor to improve the efficency of operations rooms. We apply optimization approaches to this assignment problem, for example, to reduce overtimes.
