Perhaps you should try some spelling variations:
"defined network optimisation algorithm" » "defined network optimization algorithms", "defined network estimation algorithm", "defined network estimation algorithms", "defined network optimization algorithm"
"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 ("defined network optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learning method algorithm\") OR (\"defined network optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( mapping learning method algorithm ) OR ( defined network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning method algorithm") OR ("defined network optimisation algorithm"))*.
