Perhaps you should try some spelling variations:
"modified parameter optimization algorithmsss" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameters optimization algorithmsss"
"modified objective optimal algorithm" » "modified objective optimized algorithm", "modified objective optimized algorithms", "modified objective optimizer algorithms"

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