Perhaps you should try some spelling variations:
"modified parameter optimized algorithmss" » "modified parameter optimized algorithms", "modified parameter optimizer algorithms", "modified parameter optimized algorithmsss", "modified parameter optimizer algorithmsss", "modified parameter optimization algorithmss"
"modified invasive optimized algorithm" » "modified invasive optimized algorithms", "modified invasive optimizer algorithms", "modified passive optimized 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 invasive optimized algorithm") or ("modified parameter optimized algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive optimized algorithm") OR ("modified parameter optimized algorithmss")).
• Removing quotes may allow a broader search: (( modified invasive optimized algorithm ) or ( modified parameter optimized algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive optimized algorithm") or ("modified parameter optimized algorithmss"))*.
