Perhaps you should try some spelling variations:
"modified thermal estimation algorithms" » "modified thermal estimation algorithm", "modified thermal optimization algorithms", "modified thermal optimisation algorithm", "modified thermal activation algorithms", "modified thermal oxidation algorithms"
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal 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 thermal estimation algorithms") or ("modified objective optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified thermal estimation algorithms") OR ("modified objective optimized algorithms")).
• Removing quotes may allow a broader search: (( modified thermal estimation algorithms ) or ( modified objective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified thermal estimation algorithms") or ("modified objective optimized algorithms"))*.
