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