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