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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"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"))*.
