Perhaps you should try some spelling variations:
"modified passive solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline solution algorithm"
"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 passive solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified learning method algorithm ) or ( modified passive solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning method algorithm") or ("modified passive solution algorithm"))*.
