Perhaps you should try some spelling variations:
"modified total optimization algorithmss" » "modified total optimization algorithms", "modified total optimisation algorithm", "modified total estimation algorithms", "modified total optimization algorithmsss", "modified total optimisation algorithmss", "modified total estimation algorithmss", "modified global optimization algorithmss", "modified static optimization algorithmss", "modified qoe optimization algorithmss", "modified thermal optimization algorithmss", "modified ti6al4v optimization algorithmss"
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective 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 multiobjective optimization algorithm") OR ("modified total optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"modified total optimization algorithmss\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( modified total optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("modified total optimization algorithmss"))*.
