Perhaps you should try some spelling variations:
"modified objective optimization algorithmssss" » "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective optimization algorithmsssss", "modified objective optimisation algorithmssss", "modified objective estimation algorithmssss", "modified multiobjective optimization algorithmssss"
"modified response optimization algorithm" » "modified response optimization algorithms", "modified response optimisation algorithm", "modified response 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 response optimization algorithm") or ("modified objective optimization algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified response optimization algorithm") OR ("modified objective optimization algorithmssss")).
• Removing quotes may allow a broader search: (( modified response optimization algorithm ) or ( modified objective optimization algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified response optimization algorithm") or ("modified objective optimization algorithmssss"))*.
