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