Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"machines using real algorithm" » "machinery using real algorithm", "machines using adam algorithm", "machines using search algorithm", "machines using metal algorithm", "machines using raw 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 real algorithm") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines using real algorithm") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( machines using real algorithm ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machines using real algorithm") or ("modified notion optimization algorithms"))*.
