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