Perhaps you should try some spelling variations:
international contest » international context, international contexts, international congress
based regression » based compression, data regression
contest based » content based, context based, contents based
array arcing » array forming, array probing, array sharing
arrays based » array based
arrays a » arrays _

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: international contest based regression ((((array arcing) OR (arrays a))) OR (arrays based))~.
• Adding a wildcard symbol may retrieve word variants: international contest based regression ((((array arcing) or (arrays a))) or (arrays based))*.
