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

Try widening your search to All Fields.

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 algorithm") or ("modified make optimization algorithmssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimization algorithm") OR ("modified make optimization algorithmssssss")).
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) or ( modified make optimization algorithmssssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") or ("modified make optimization algorithmssssss"))*.
