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