Perhaps you should try some spelling variations:
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified location optimization algorithms"
"model learning method algorithm" » "model learning mom algorithm", "model learning methods algorithm", "model graining methods algorithm", "model learning emotion algorithm", "mobile learning method algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified allocation optimization algorithms") OR ("model learning method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified allocation optimization algorithms\") OR (\"model learning method algorithm\"))".
• Removing quotes may allow a broader search: (( modified allocation optimization algorithms ) OR ( model learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithms") OR ("model learning method algorithm"))*.
