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"
"coarse learning method algorithm" » "coarse learning mom algorithm", "coarse graining method algorithm", "coarse learning methods algorithm", "coarse graining methods algorithm", "coarse learning emotion algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified notion optimization algorithms") or ("coarse learning method algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion optimization algorithms") OR ("coarse learning method algorithm")).
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) or ( coarse learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") or ("coarse learning method algorithm"))*.
