Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified caging predation algorithm" » "modified caging predators algorithm", "modified caging estimation algorithm", "modified aging predation algorithm", "modified changing predation algorithm", "modified charging 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 caging predation algorithm") OR ("modified notion optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified caging predation algorithm\") OR (\"modified notion optimization algorithms\"))*".
• Removing quotes may allow a broader search: (( modified caging predation algorithm ) OR ( modified notion optimization algorithms ))*.
