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"
"mapping learning methods algorithm" » "machine learning methods algorithm", "enabling learning methods algorithm", "mapping nursing methods algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping learning methods algorithm") OR ("modified notion optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learning methods algorithm\") OR (\"modified notion optimization algorithms\"))*".
• Removing quotes may allow a broader search: (( mapping learning methods algorithm ) OR ( modified notion optimization algorithms ))*.
