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"
"modified write estimation algorithmss" » "modified write estimation algorithms", "modified write estimation algorithm", "modified write optimization algorithms", "modified risk estimation algorithmss", "modified pose estimation algorithmss"

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: (("modified network optimization algorithm") or ("modified write estimation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimization algorithm") OR ("modified write estimation algorithmss")).
• Removing quotes may allow a broader search: (( modified network optimization algorithm ) or ( modified write estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithm") or ("modified write estimation algorithmss"))*.
