Perhaps you should try some spelling variations:
applications optimization » applications application, applications identification, applications communication
optimization system » optimization systems, optimization scheme, optimization swarm
array probing » arrays probing, assay probing, array profiling
array sharing » arrays bearing, array imaging, way sharing
array string » array strong, arrays strings, array forming
system r » system re, system ras, system rms

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

• Performing a fuzzy search may retrieve terms with similar spellings: applications optimization system r ((((array string) or (array probing))) or (array sharing))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: applications optimization system r ((((array string) OR (array probing))) OR (array sharing)).
• Adding a wildcard symbol may retrieve word variants: applications optimization system r ((((array string) or (array probing))) or (array sharing))*.
