Perhaps you should try some spelling variations:
"modified allocation estimation algorithms" » "modified allocation optimization algorithms", "modified motion estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimisation algorithm"
"modified adam optimizer algorithms" » "modified adam optimized algorithms", "modified adam optimized algorithm", "modified adam optimization algorithms", "modified df optimizer algorithms", "modified near optimizer algorithms"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adam optimizer algorithms") OR ("modified allocation estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified adam optimizer algorithms ) or ( modified allocation estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam optimizer algorithms") or ("modified allocation estimation algorithms"))*.
