Perhaps you should try some spelling variations:
"modified network estimation algorithmssss" » "modified network estimation algorithms", "modified network estimation algorithm", "modified network optimization algorithmssss", "certified network estimation algorithmssss", "defined network estimation algorithmssss", "modified near estimation algorithmssss"
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"

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