Perhaps you should try some spelling variations:
"modified total optimization algorithms" » "modified total optimisation algorithm", "modified total estimation algorithms", "modified total estimation algorithm", "modified total optimisation algorithms", "modified total estimation algorithmss", "modified global optimization algorithms", "modified static optimization algorithms", "modified qoe optimization algorithms", "modified thermal optimization algorithms", "modified ti6al4v optimization algorithms"
"modified multiobjective optimization algorithm" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified total optimization algorithms") OR ("modified multiobjective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified total optimization algorithms\") OR (\"modified multiobjective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified total optimization algorithms ) OR ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified total optimization algorithms") OR ("modified multiobjective optimization algorithm"))*.
