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