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"
"code learning method algorithm" » "code learning mom algorithm", "code learning methods algorithm", "code graining methods algorithm", "code learning emotion algorithm", "how learning 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: (("code learning method algorithm") OR ("modified notion optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code learning method algorithm\") OR (\"modified notion optimization algorithms\"))".
• Removing quotes may allow a broader search: (( code learning method algorithm ) OR ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("code learning method algorithm") OR ("modified notion optimization algorithms"))*.
