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