Perhaps you should try some spelling variations:
"modified parameter optimized algorithm" » "modified parameter optimization algorithm", "modified parameter optimized algorithms", "modified parameter optimizer algorithms"
"modified objective allocation algorithmsss" » "modified objective location algorithmsss", "modified objective allocation algorithms", "modified objective allocation algorithmic"

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