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"

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"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"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"))*.
