Perhaps you should try some spelling variations:
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"
"modified caging optimizer algorithms" » "modified caging optimized algorithms", "modified caging optimized algorithm", "modified caging optimization algorithms", "modified choosing 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 caging optimizer algorithms") OR ("modified notion estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified caging optimizer algorithms ) or ( modified notion estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimizer algorithms") or ("modified notion estimation algorithms"))*.
