Perhaps you should try some spelling variations:
"modified make estimation algorithmssssss" » "modified make estimation algorithms", "modified make estimation algorithm", "modified pose estimation algorithmssssss", "modified male estimation algorithmssssss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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

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