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