This repository contains the Julia sources for my solution to the Kaggle Packing Santa's Sleigh competition. The challenge consisted of packing one million presents of varying sizes in delivery order into Santa's fixed length and width sleigh with the least height. The task is essentially a bin packing problem with the ordering constraint making it more like a cutting stock problem.
The primary file is src/packPresents.jl which implements
of a two dimensional shelf algorithm augmented by a height compaction
algorithm.
The file src/experimental.jl contains code for
other approaches that were not used in the final solution. Included is
code to determine the
minimum cover of a set of rectilinear rectangles.
The file solviewer/solviewer.pde contains the sources for a simple
solution viewer written in
Processing. The viewer was used during
early development and is limited to visualizing a few thousand
presents. The following screenshot shows an example visualization.
