Perhaps you should try some spelling variations:
"modified make optimization algorithmssss" » "modified make optimization algorithms", "modified make optimisation algorithm", "modified market optimization algorithmssss", "modified game optimization algorithmssss", "modified stage optimization algorithmssss", "modified male optimization algorithmssss"
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective estimation algorithms") or ("modified make optimization algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective estimation algorithms") OR ("modified make optimization algorithmssss")).
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithms ) or ( modified make optimization algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithms") or ("modified make optimization algorithmssss"))*.
