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