Perhaps you should try some spelling variations:
"modified location optimization algorithms" » "modified location optimisation algorithm", "modified location estimation algorithms", "modified location estimation algorithm", "modified allocation optimization algorithms", "modified static optimization algorithms", "modified carbon optimization algorithms"
"mapping learning method algorithm" » "machine learning method algorithm", "enabling learning method algorithm", "mapping learning mom algorithm", "mapping learning methods algorithm", "mapping graining methods algorithm", "mapping learning emotion 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 method algorithm") OR ("modified location optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learning method algorithm\") OR (\"modified location optimization algorithms\"))".
• Removing quotes may allow a broader search: (( mapping learning method algorithm ) OR ( modified location optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning method algorithm") OR ("modified location optimization algorithms"))*.
