Perhaps you should try some spelling variations:
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal algorithms"
"machines using raw algorithm" » "machinery using raw algorithm", "machines using adam algorithm", "machines using _ algorithm", "machines using mom algorithm", "machines using real algorithm", "machines using a algorithm", "machines using low algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("machines using raw algorithm") OR ("modified objective optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machines using raw algorithm\") OR (\"modified objective optimized algorithms\"))".
• Removing quotes may allow a broader search: (( machines using raw algorithm ) OR ( modified objective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machines using raw algorithm") OR ("modified objective optimized algorithms"))*.
