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