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