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