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