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