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