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