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 fire predation algorithm" » "modified fire predators algorithm", "modified fire estimation algorithm", "modified fire prediction algorithm", "modified seird predation algorithm", "modified bi1 predation algorithm", "modified male 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 notion optimization algorithms") OR ("modified fire predation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion optimization algorithms\") OR (\"modified fire predation algorithm\"))".
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) OR ( modified fire predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") OR ("modified fire predation algorithm"))*.
