Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"machines focusing method algorithm" » "machines using method algorithm", "machines focusing mom algorithm", "machines forecasting method 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 focusing method algorithm") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines focusing method algorithm") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( machines focusing method algorithm ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machines focusing method algorithm") or ("modified notion optimization algorithms"))*.
