Perhaps you should try some spelling variations:
"modified choosing estimation algorithmss" » "modified choosing estimation algorithms", "modified choosing optimization algorithms", "modified caging estimation algorithmss"
"modified allocation estimation algorithm" » "modified allocation optimization algorithm", "modified motion estimation algorithm"

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 choosing estimation algorithmss") OR ("modified allocation estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified choosing estimation algorithmss ) or ( modified allocation estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified choosing estimation algorithmss") or ("modified allocation estimation algorithm"))*.
