Perhaps you should try some spelling variations:
"modified parameters estimation algorithmsss" » "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter estimation algorithmsss", "modified parameter estimates algorithmsss", "modified parameter optimization algorithmsss"
"modified objective predators algorithm" » "modified objective 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 objective predators algorithm") OR ("modified parameters estimation algorithmsss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective predators algorithm\") OR (\"modified parameters estimation algorithmsss\"))".
• Removing quotes may allow a broader search: (( modified objective predators algorithm ) OR ( modified parameters estimation algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective predators algorithm") OR ("modified parameters estimation algorithmsss"))*.
