In this paper, we analyze the complexity of the gear placement problem (GPP). In the GPP, we are given a rectangular plane, called a gearbox, on which a torque generator source and a set of gears, called target gears, are placed. The task is to find

The rectilinear block packing problem is a problem of packing a set of rectilinear blocks into a larger rectangular container with fixed width and unrestricted height. A rectilinear block is a polygonal block whose interior angles are either 90◦ or

In this paper, we propose a heuristic algorithm for a container loading problem for logistic platforms, which is the problem for the Challenge Renault/ESICUP 2015. The three-dimensional container loading problem involves packing a set of cuboid items

In this paper, we study an operational planning and scheduling problem in an automatic picking system. This problem was introduced as a practical benchmark problem arising in logistics and involves assignment and scheduling tasks. We first show the N

The lexicographic bi-criteria combinatorial optimization problem to be discussed in this paper is a mathematical model of the food mixture packing performed by so-called automatic combination weighers, and it is described as follows. We are given a u

In the Escherization problem, given a closed figure in the plane, the objective is to find a closed figure that is as close as possible to the input figure that tiles the plane. Koizumi and Sugihara’s formulation reduces this problem to an eigenval

This paper focuses on a two-dimensional strip packing problem where a set of arbitrarily shaped rectilinear blocks need be packed into a larger rectangular container without overlap. A rectilinear block is a polygonal block whose interior angles are
