Perhaps you should try some spelling variations:
"modified notion optimization algorithmsss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified network optimization algorithmsss", "modified policy optimization algorithmsss", "modified allocation optimization algorithmsss"
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"

Try widening your search to All Fields.

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 predation algorithm") or ("modified notion optimization algorithmsss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective predation algorithm") OR ("modified notion optimization algorithmsss")).
• Removing quotes may allow a broader search: (( modified objective predation algorithm ) or ( modified notion optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective predation algorithm") or ("modified notion optimization algorithmsss"))*.
