Perhaps you should try some spelling variations:
"modified motion estimation algorithms" » "modified motion estimation algorithm", "modified motion optimization algorithms", "modified motion optimisation algorithm", "modified notion estimation algorithms"
"modified caging optimized algorithm" » "modified caging optimized algorithms", "modified caging optimizer algorithms", "modified aging optimized algorithm", "modified changing optimized algorithm", "modified charging optimized algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified caging optimized algorithm") OR ("modified motion estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified caging optimized algorithm\") OR (\"modified motion estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified caging optimized algorithm ) OR ( modified motion estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimized algorithm") OR ("modified motion estimation algorithms"))*.
