SUNNY-AS for OASC challenge

This programm is an extension of the SUNNY-AS tool, available at CP-UNIBO.

We integrated a training phase for SUNNY, and we proposed two modalities: autok and fkvar. "autok" studies only the neighbourhood value k, "fkvar" accounts for both k and features. For more details please refer to description.



The source codes of SUNNY and training are contained in the folder 'src' and 'oasc' respectively. The folder 'main' contains the scripts to run different modalities of SUNNY on all scenarios.

The program runs training and testing in sequence, in following we take 'autok' approach as execution example:

  1. Training:

Go to the 'main' folder.

 main:$~ sh > tasks.txt 
 main:$~ sh run_autok tasks.txt # configured for parallel execution

Training results would be stored in the corresponding folder and will be read automatically by test scripts

  1. Testing:
 main:$~ sh > tasks.txt 
 main:$~ sh autok tasks.txt # configured for parallel execution

For the other approach 'fkvar', it is sufficient to substitute 'autok' for 'fkvar', thus, the following commands:

 main:$~ sh > tasks.txt 
 main:$~ sh run_fkvar tasks.txt # configured for parallel execution
 main:$~ sh run_fkvar tasks.txt # configured for parallel execution

Note that,

  • The two training modalities should run separately.
  • In 'oasc' folder, you can also run SUNNY on a single scenario as follow (e.g. scenario 'Caren'):
 oasc:$~ python Caren # training,
 oasc:$~ python Caren autok # testing
