Perhaps you should try some spelling variations:
"modified make optimization algorithmss" » "modified make optimization algorithms", "modified make optimisation algorithm", "modified make estimation algorithm", "modified market optimization algorithmss", "modified game optimization algorithmss", "modified stage optimization algorithmss", "modified male optimization algorithmss"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation 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 estimation algorithms") OR ("modified make optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective estimation algorithms\") OR (\"modified make optimization algorithmss\"))".
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) OR ( modified make optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") OR ("modified make optimization algorithmss"))*.
