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 caging optimized algorithms" » "modified caging optimized algorithm", "modified caging optimizer algorithms", "modified caging optimization algorithms", "modified aging optimized algorithms", "modified changing optimized algorithms", "modified charging optimized algorithms"

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