Given a set of rectangles and a rectangular container with a fixed width, called a strip, the twodimensional strip packing problem (2SP) requires all the given rectangles to be placed orthogonallyâ€¦ (More)

The irregular strip packing problem is a combinatorial optimization problem that asks to place a given set of 2-dimensional polygons within a rectangular container so that no polygon overlaps withâ€¦ (More)

We examine various strategies for exact approaches to the 2dimensional strip packing problem (2SP) with and without rotations of 90 degrees. We first develop a branch-and-bound algorithm based on theâ€¦ (More)

IBM Mega Traffic Simulator (Megaffic) is an agent-based simulator of traffic flows with two unique features. First, Megaffic can build its model of simulation by directly estimating some of theâ€¦ (More)

We propose exact algorithms for the 2-dimensional strip packing problem (2SP) with and without 90 degrees rotations. We first focus on the perfect packing problem (PP), which is a special case ofâ€¦ (More)

We have devised a method to generate non-overlapping random dot patterns for light guides and diffuser films in liquid crystal displays (LCDs). Molecular-dynamics-based algorithms are being for thisâ€¦ (More)

Optimizing city transportation for smarter cities can have a major impact on the quality of life in urban areas in terms of economic merits and low environmental load. In many cities of the world,â€¦ (More)
