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"
"machines forecasting method algorithm" » "mapping forecasting method algorithm", "machines focusing method algorithm", "machines forecasting mixed algorithm", "machines forecasting mom algorithm"

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

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