Perhaps you should try some spelling variations:
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation algorithm"
"mapping learning method algorithm" » "machine learning method algorithm", "enabling learning method algorithm", "mapping learning mom algorithm", "mapping learning methods algorithm", "mapping graining methods algorithm", "mapping learning emotion 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: (("mapping learning method algorithm") or ("modified network optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mapping learning method algorithm") OR ("modified network optimisation algorithm")).
• Removing quotes may allow a broader search: (( mapping learning method algorithm ) or ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning method algorithm") or ("modified network optimisation algorithm"))*.
