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"
"core learning method algorithm" » "core learning mom algorithm", "core learning methods algorithm", "core graining methods algorithm", "core learning emotion algorithm", "how learning method algorithm"

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

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