Implementation of the Acquire Valued Shoppers Challenge in C++.

Usage: ./shopper-hivemind [options]

General options:
  -h [ --help ]          display this message
  -c [ --cache ]         generate cache files,  if they do not exist yet
  -p [ --clear-cache ]   clears cache files (will ask for confirmation)
  -t [ --debug ]         use small debug subset, for code testing purposes
  -f [ --force ]         will never ask confirmation, answer [YES] to 
                         everything
  -d [ --datadir ] arg   specify in which directory to search for the data 
                         files (default ./data)
  -a [ --algorithm ] arg {svm, linear} (defaults to svm)

shopper-hivemind can be compiled using at least Clang 3.2 or higher.

Compilation has been tested with the following setups:

• Ubuntu 13.10, Clang 3.2
• Ubuntu 14.04, Clang 3.4

This software project uses the following packages:

• Boost with {system, filesystem, regex, program_options, iostreams}
• Msgpack
• LibSVM
• LibLinear
• Qt5

To install the software required to compile shopper-hivemind on Ubuntu, use the following commands:

# apt-get update
# apt-get install libboost-dev libboost-system-dev libboost-filesystem-dev libboost-regex-dev libboost-program-options-dev libboost-iostreams-dev libmsgpack-dev libsvm-dev qtbase5-dev

You then still need to install liblinear, which can easily be downloaded by running:

$ git submodule sync
$ git submodule update --init

See contrib/liblinear for details on how to build and install liblinear.

shopper-hivemind can be built using both qmake and cmake. For qmake, just install QtCreator and load the .pro-file. For cmake, run:

$ ./cmake-linux
$ cd build
$ make

To retrieve the source data, including the (partial) cached files, run

$ ./download-data

This will use up approximately 8.7GiB of disk space, so beware. When testing, try first to run with the --debug cli option. This will force the algorithm to use a random subset of the dataset.
