Perhaps you should try some spelling variations:
optimization exploiting » optimization applying, optimization developing, optimization extending
exploiting method » exploring methods, exploiting meta, exploiting motion
array formulas » area formulas, harrop formulas, array format
array probing » arrays probing, assay probing, array profiling
method tools » methods tools, method two
array string » array strong, arrays strings, array sharing

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

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