Perhaps you should try some spelling variations:
"modified response optimization algorithmssss" » "modified response optimization algorithms", "modified response optimisation algorithm"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation 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 allocation algorithm") OR ("modified response optimization algorithmssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective allocation algorithm\") OR (\"modified response optimization algorithmssss\"))".
• Removing quotes may allow a broader search: (( modified objective allocation algorithm ) OR ( modified response optimization algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithm") OR ("modified response optimization algorithmssss"))*.
