Perhaps you should try some spelling variations:
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization algorithm"
"enabling learning method algorithm" » "mapping learning method algorithm", "enabling learning mom algorithm", "enabling learning methods algorithm", "enabling graining methods algorithm", "enabling learning emotion algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("enabling learning method algorithm") or ("modified network optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("enabling learning method algorithm") OR ("modified network optimization algorithm"))*.
• Removing quotes may allow a broader search: (( enabling learning method algorithm ) or ( modified network optimization algorithm ))*.
