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