Perhaps you should try some spelling variations:
"modified total optimization algorithms" » "modified total optimisation algorithm", "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 objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimisation algorithm", "modified objective approximation algorithms", "modified objective optimization algorithms", "modified objective allocation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective estimation algorithms") or ("modified total optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective estimation algorithms") OR ("modified total optimization algorithms")).
• Removing quotes may allow a broader search: (( modified objective estimation algorithms ) or ( modified total optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithms") or ("modified total optimization algorithms"))*.
