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 using method algorithm" » "machines using mom algorithm", "machinery using method algorithm", "machines nursing methods algorithm", "machines focusing method algorithm", "machines using metal 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 using method algorithm") OR ("modified notion optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machines using method algorithm\") OR (\"modified notion optimization algorithms\"))*".
• Removing quotes may allow a broader search: (( machines using method algorithm ) OR ( modified notion optimization algorithms ))*.
