Perhaps you should try some spelling variations:
"modified parameter optimized algorithm" » "modified parameter optimization algorithm", "modified parameter optimized algorithms", "modified parameter optimizer algorithms"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"

You may be able to get more results by adjusting your search query.

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