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