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