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"
"powder using real algorithm" » "powder using adam algorithm", "powder using search algorithm", "code using real algorithm", "boiler using real algorithm", "model using real algorithm", "powder using metal algorithm", "powder using raw algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("powder using real algorithm") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("powder using real algorithm") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( powder using real algorithm ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("powder using real algorithm") or ("modified notion optimization algorithms"))*.
