Perhaps you should try some spelling variations:
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation algorithm"
"modified model estimation algorithm" » "modified pose estimation algorithm", "modified cover estimations algorithm", "modified motion estimation algorithm", "modified male estimation 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: (("modified model estimation algorithm") or ("modified network optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified model estimation algorithm") OR ("modified network optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified model estimation algorithm ) or ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified model estimation algorithm") or ("modified network optimisation algorithm"))*.
