Input examples

Download input files for all examples at once:
tar.gz file: examples.tar.gz
zip file: examples.zip

Both clean and commented input files can be used.

Important: If you are using Windows or DOS and you get some input/output error when using these files, open each file in the wordpad, save them as "txt" and try again.

These examples were run in a VAIO NR11Z/S laptop. Times may vary for similar problems depending on how hard is to find the packing solution.
