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